It works
September 29, 2019
Putt for dough! Been using this for years. I believe it helps and use it on the mostly for putting. With good greens, the ball rolls evenly on the balance line. Breaking putts more tricky. On full shots, it seems to help although the quality of the swing matters more.
ProsGreat value (you can't make one yourself for the same price). Uses batteries and portable.
ConsTakes skill and time to mark the balls. I try to lightly mark the spinning ball (in the middle), then use a line marker and permanent marker pen to make the final total or partial line.

Check-go great, $12 marker sucks!
May 27, 2019
The Check-Go works as advertised, but the marker that came with it was so old, dry and hard, you could use it as a nail punch. Replacement markers are ridiculously expensive. And please hold the "customer service will contact you" schtick, that has NEVER happened!!
Merchant Response:Thank you for the feedback! The customer service crew has been notified of your issue and will be reaching out to help. I am sorry for the inconvenience.

Alignment Made Easy
November 7, 2017
I'm not sure yet how much it will help my drives as I believe club face to ball at contact determines the final outcome of the flight path of the ball. I do like the alignment line from using the Check-GoPro when I'm setting up to putt. It gives me a better sense of the alignment of the putter to the ball and how I've read the ball path on the green to the cup. So far so good.
ProsThe Check-GoPro is an easy to use product and has worked just as I had expected.
ConsNot sure how long the pen is going to last and they seem to be expensive to replace. I understand the reasoning behind making it to be the only one to be able to use. Still would like to be able to use a "Sharpie" if I wanted to.

Great Product that Everyone Should Have
July 22, 2017
My instructor recommended that purchase one to help with alignment. I was skeptical, but I went ahead and ordered. I had always used the stamp on the ball to help with alignment. I am extremely satisfied with the Technasonic Golf Check-Go Pro. This has really helped me with alignment while playing and putting. Thanks Rock Bottom Golf for delivering another great product.
ProsEasy to use Inexpensive Definitely helps to lower scores

Great Product
February 7, 2017
I had a similar product that was no were near as good as this. I find using this to insure the ball is true when hitting or putting is the best way to insure of that. Product gives you different options on marking witch in turn is ideal.
ProsGreat for putting and making sure ball rolls true and straight. Makes alignment for drives off tee easy, pick your landing area/ target and line up with marking on ball!.
ConsHave not found one

Using the Technasonic
February 7, 2017
Technasonic ball marker is easy enough to use but takes a little practice. You have to make sure the marker pen straight when you insert it into the hole. Otherwise, even though it marks the balance center, the line will not be on the exact equator of the ball. Therefore, when you line it up to putt it looks off center but will track straight. I marked a bag (48) of recycle balls and got the majority marked correctly. It just takes a little practice so I suggest you start with old balls till you get it right. I helps to rotate the top (where the hole is) 90 degrees to the start button and have it at a level where you can see the position of the pen. I put it on a table so I could sit in a chair and easily see the pen.
ProsHandy device for finding the balance center of the ball and does help with lining up a putt. Now if I could just putt :)
ConsCan't use any other marker pen than the one supplied and the ink is not that good. Tends to wear off easily and will leave a mark on the club face when hit with any other club than the putter. Also, I found it difficult to make a mark in option 4 (see instructions) without the ink splattering.

Nice spinner

This new model is quite a bit better than then old. The light for full speed is nice.
ProsLooks better, light for full spin speed.
By Richie
July 19, 2016
While I cannot prove the results I do believe this helps for two reasons. 1) When I have a great drive (draw and run out) I find the circle on the ball is constantly lined up with the flight path and the dot is on the same side as when teed up. So the ball must find it's ideal center of rotation. 2) When I tee the ball up, my confidence is up, due to the results in #1.... I know everything outside of my swing is working for me.
ProsConfidence increases
ConsSmall hole does not allow for std., fine Sharpie to be used. Need to buy their replacement (I have not fully researched other marker options)

I read a lot of reviews on center ball mass and finding the center line. Well this product does a great job. I was very skeptical at first but I tested this at least a dozen times and it found the same spot every time. I am glad I purchased this now!

March 14, 2016
You have to hold the top cover down because the ball will spin so fast it bounces around and cause the top to come loose, or the ball flies out.
ProsIt is pretty accurate

December 13, 2015
Don't trust the lines put on your balls by manufacturers, I've checked them all, Titliest, Nike, Pinnacle, Bullet, and out of 350 balls, only 2 were lined up correctly, and that's probably statistics and probability, mark your balls using this or blame your missed putts on the ball
ProsSpins quietly, takes 5 seconds to reach max speed

Others told me that using this tool had helped them. It was a good price at RBG so I figured why not. I doubt it helps with anything but putting, but I can sure say that my putting has improved since using this, which has helped lower my scores. Definitely practice on some old balls to get the hang of it.

ConsMust use Techasonic's markers.

July 1, 2015
Quite a unique tool that seems to do what it describes! Tested it on various brands...Titliest must already do something like this before adding markings to the ProV1 as it indicated same zone what is already on the ball! Any other make came up with its own spot.

Jury out
May 4, 2015
I can't say i am a better putter due to this and just not positive all the reasons I need this are really necessary. I don't really like lines on my balls ( just confuses me more !) so not sure exactly why I got this but I do manually put a small mark after spinning so I guess if I am confident my ball is correctly balanced, I should be more confident in my putting?

zero relation between ball printing and balance
February 19, 2015
really quick and easy to use. most consistent results obtained when used on a dead level surface. redid many balls as an experiment-variations noted(smaller than i would've expected) on not quite level surfaces and got many dead matches after finding a perfectly flat area with a level. do not know if it will make a noticable difference in reality out on the course, but, physics-wise the concept is sound. you can make a med. fine sharpie work by using a file to evenly remove plastic until it extends in far enough to contact the ball. very light touch works best with marker provided unless you don't mind alot of spiderwebbing from spin-off.
Prosquick- up to speed in less than 10 sec.

September 12, 2014
The Go Pro works as described and seems to deliver consistent results. Using the pen can be a bit messy until you get used to it. Birdied my first hole using a checked ball, not sure if this proves anything but a good start and will be interesting to see how the balls perform over time.

Does what it says
August 27, 2014
It does exactly what it says it will do, I'm just not sure what effect the line has since I cant run any trials with the without the line. If nothing else it does provide a very crisp line to line up putts. I just dont understand why the big guys dont already do it for all their balls.
ConsTime consuming - not terrible - just that it has to be done

Wow what a gadget!
May 16, 2014
Does everyone feel they need one? Well no, but after using it, driving a marked ball, and of course putting with a marked ball...I cannot think of playing without a "Checked" ball! If I feel that the ball is rolling better on whatever line I chose and I am either dropping the putts or at least getting them gimmie lengths; then this gadget is a keeper. I am a bowler (186 Avg) as well as a golfer; and the core and cg point are critical to getting the bowling ball to roll how I want it to roll; so why wouldn't that same logic apply to the golf ball! It only takes a matter of seconds to find the axis of each individual ball I use, so I have the mental confidence that I have done everything possible to give me that extra edge over my golf buddies!
ProsOnce you get the hang of how hard to press the marker into the holes to cause a mark to be made, marking the ball becomes second nature.
Consthe cap on the marker falls off to easy; then dries out becoming useless. Technasonic cannot be making that much money on the markers so as to not make the hole capable of using a sharpie or some other brand of marker. Without having a usable marker the device becomes garbage.

Ball rolls true when putting
April 3, 2014
Purchased this a week ago and I marked a few balls and played them a couple of days ago. I have a natural fade to my shots and when hitting off the tee, I noticed that the ball faded less but when I hit from the fairway and the line on the ball was not in line with my shot, my normal fade appeared. This proved to me that there is a difference in ball balance and when you spin it on this machine you can really tell how out of balance the balls can be. I don't like the top marking feature because it splatters the ink when you touch the ball....makes a mess.
ProsReally does balance the ball. Driving and putting is really helped the most
ConsSpecial pen must be used. Tried to experiment with a Sharpie and could not make it work.

Interesting Product
December 6, 2013
Received this as a gift and it was the perfect gift because this isn't something that I would buy for myself. It will take some practice when it comes to marking balls, especially if you want to make a line all the way around the ball. A lot of smears can occur if pen pressure is too light or heavy. I personally don't like a line all the way around my ball because it bothers my eye when hitting approach shots when you can't touch your ball to realign it. This is a method I have started using with success. I'll find one balance point (top slot) and mark that with a dot. I'll then remove the ball and put the dot i just found downward onto the spindle to find the balance point on the other side of the ball. So with the two dots marked I take my plastic ball liner and align that up with 2 points and mark a smaller line on the ball that I prefer. With that said I did see some improvement in accuracy with tee shots and some putting improvement. While I've always drawn a short line on my ball to help alignment the new line seems to be helping a bit. Maybe it's mental maybe not but I'll take what I can get! Been hitting a couple more fairways per round and also making a couple more putts per round so I am pleased. Neat product and like I said, makes a great gift.
