Check Go Electronic Ball Liner

This marker worked well and did everything I expected it to do. I would suggest putting a mat of some kind under it before starting it will mark a table top. I recieved it in good time.

I find it to be accuarte. I can repeat the process with the same ball and get the same results. My last unit had a green light to indicate when the unit was up to speed but this one is missing that feature It is not essential but it speeds things up a little and saves some battery life since you don't need to wait a long time to make sure the unit is ready for marking. My one compliant is the marking pen. Both units I have bought came with a pen that was almost dry, didn't mark well and was totally shot after a few balls. Normal markers will not fit in the holes so you are stuck ordering very expensive replacement pens and feeling ripped off.

Tested same ball several times to determine consistency of results. Excellent results from test to test! Not sure if it has helped my putting, but has increased my confidence in the ball roll.

I've played only 3 times using the balls marked with the Check-GO. I played very well the first time, scoring lower than I had in months. The second time was average and the third was in a scramble where I putted as well as I ever have. Do I attribute the putting changes to the Check-GO? Can't say. But, it does seem to do what they say it does. It works just as it is designed to work and you get a ball that is marked with a line around it.

Concept sounds great. However like many others have stated the pen is a joke. Would not write and replacement pens are ridiculously expensive for such a pipsqueak pen. I tried to use a sharpie fine tip and all I got was a wiggle line. If you want something that purports to be a quality golf product, don't buy this thing.

Assist in lining up the ball and gives great feedback on your putting strike. If it really balances your ball ... that's a bonus!

Pretty good~
