Rated 5 out of 5 by R_P_H A very nifty self-teaching gadget
I preface this review with an acknowledgement that I, like many other beginners, would surely benefit more from daily or weekly professional instruction than by using a gadget, however good it might be. I also acknowledge that the true test of the value of either lessons or self-instruction is one's performance on the golf course. Time will tell for me whether the 3 Bays GSA Pro will have helped me bring down my stubbornly high handicap. All of this said, my short but intensive use of the GSA Pro has confirmed to me that this self-teaching tool just may be helpful. I think it is a very good tool.
So why is it so good? First, it seems to yield pretty accurate data on one's swing. Not prepared to take at face value the numerous YouTube videos demonstrating the relative accuracy of the GSA Pro, I compared its measurements with those provided by the multi-thousand dollar simulator at a nearby Dick's Sporting Goods. I was amazed at the comparability of the measurements; tempo, carry distance, club speed, and face angle and swing path were all extremely close to the measurements of the larger and costly simulator, and often identical.
Second, the iPhone APP allows the golfer to video his/her swings. This is immensely helpful in diagnosing one's swing in combination with the data delivered by the GSA Pro. Although the simulated swing arc provided by the GSA Pro provides very useful instant feedback, I think that it's much much more helpful when viewed together with the video of one's self. Admittedly, self-diagnosis is only possible if one has learned the basics of the golf swing; I rely very heavily on Ben Hogan's The Modern Fundamentals of Golf. The GSA Pro can't tell the golfer how to fix the swing; it can only give him/her quantitative indicators (e.g., whether the swing is outside-in, and/or of the club face is square or open or closed), and some visual feedback (as with the simulated swing and/or self-video). But used in conjunction with knowledge of how to remedy problems with one's swing, the GSA Pro appears to be an ideal tool for self-improvement.
Third, it seems to provide a way to practice one's swing at home. Rather than swing pointlessly in one's living room [and then claiming that all those balls were straight and long! :-)], the GSA Pro provides instant feedback that characterizes how the ball would have been struck, how far it might have gone, etc. My experience so far suggests to me that the GSA Pro's best use is at the driving range. Moreover, some measurements seem to differ at home (where one is only swinging the club) from those ago the driving range. For instance, my club speed is systematically greater at the driving range--for all clubs--than in my basement. I suspect this is because, despite having high enough ceilings, I am a little less bold in my swing when indoors. Nevertheless, I am using it avidly indoors anyway, and to good effect so far.
Everything seems to have been really well thought out in terms of engineering and software. Indeed, the APP is superb. So far, my only suggestion for an improvement to the APP is for one to be able to delete all swings recorded for any specific club. At present, one can only delete swings one-by-one. That can take time to carry out if there are, say, 30 or 40 swings already recorded and stored.
All in all, this gadget does what it is advertised to do, and I am very pleased with it so far. Time will tell if it has helped my on-course performance.
I recommend it very highly to any golfer who already has a good understanding of the mechanics of the golf swing.

It's not a bad product. Does give useful information but you have to hold the club still for 1.5 seconds before starting your back-swing which means no waggling the club or taking a quarter back swing to see if the sweet-spot is in line for the real swing. It is very hard for me not to waggle the club and just start the back-swing from a still position.

Rated 4 out of 5 by Hacker Bill Some features worked well
Tried the analyzer at a driving range to check clubhead speed. Did a nice job. Club face position at impact needed adjustment as my driver has no alignment arrow to match the arrow on the analyzer. Had some initial problems syncing with IPad, but they were overcome with numerous tries. Image size is fixed to match phone image and doesn't adjust. So a large IPad/IPod will not display an enlarged image. The backswing/downswing ratio seem to be true. The ball distance estimate was long when using range balls. Didn't use it on a golf course. Overall, it worked almost as advertized. I found that using an analyzer was a bit distracting when adjusting my swing because I was aware it was recording, and that reduced my concentration on the shot. A bit pricey, but useful.

This product is not great.
Hard to use.
Would not record all my swings.
Sometimes it records, sometimes not.
Inconsistent recording, not worth the money.
