Question: Do you need cellular service for this to work, or would it work on an iPad through bluetooth on the golf course?
Document: This golf analyzer would not recognize my iPod touch 5th Gen. Site said it would. Also would not sync with Bluetooth feature on my Samsung tablet. Tried to contact company through their email, no tell #, wrote twice, no response. I would not recommend this product simply because of the poor customer service and it does not perform as advertised.
The product itself is very good. However, ever since my iPhone 5 software was upgrade to IOS 7. It fails to connect to bluetooth, even tho it is paired with that iPhone. It worked perfectly under IOS 6. I have written to the company twice, using their Support website and have heard nothing, not even an acknowledgment of the emails. I would give this a 5-star rating but for this very poor customer service.
this product is horrible, i followed all the instructions and was not able to make this device work. there is know way to contact anyone from customer service except through email and they never responded, i would not recommend this product .
This analyzer helps a returning marginal golfer like myself. Easy to line up and secure on shaft -- actually don't need to use built-in sight just square up the top of unit to the clubhead. Connects easily to cell phone bluetooth. Gives a reasonably clear picture of my faults in the swing not otherwise available unless an instructor views me. For the cost, it is very useful. If it could only make my swing it would be ideal...
I've never been able to consistently take golf lessons nor do I have the time between work and family. But this is like a golf coach while you are on the course with your buddies for a whole lot less cash. This is a must have for any golfer.Update...I downloaded the update to the new app, there are some great new features. I can now record my swings via video and review them later w the swing analysis. Pretty cool new feature.
The concept for this device is great and the information it provides is helpful....if you can get it to work. I received my first one and the battery would not last for more than 15 swings when using video (their email comment &#34;Assuming the sensor is fully charged, you should be able to get 500 to 600 swings&#34;). Called customer service (David) and they gave me some tips that didn't work.
Clearly there are issues with this device. After looking at other reviews its seems there are a number of performance complaints. Mine worked fine for 2 swings, but after that it can not complete a swing download. The swing starts to load and then the bluetooth connection gets lost at the very end - happens pretty much every time, then the device immediately pairs again. Might be a good product if they would get it to work. I contacted customer care, still waiting to hear back.
This is an product that will change the way newbies or experienced folks will golf. Walking onto the course with swing tip sure grabs attention. I was so convinced about its usefulness that i have recommended this to a bunch of my other buddies.The only thing I would request from this excellent startup company with the innovative products is to add more instructional videos for new learners.
Could not get it to work on the ipad so I returned it. I did call the manufacture with no luck.
This is a good product. Using it with my iPhone and iPad Mini. Had a question about Bluetooth connectivity, sent email and question answered same day.Lost sight off of saddle, my own fault, not the product. Emailed about buying a replacement, and they sent a replacement gratis.Can't think of one thing to say that is not positive. Just purchased new clubs and using this to help dial in yardages.
Answer: yes
