Input:
Question: I was reading that you have to log into their website when you use the device. Why?  Do you have to have an Internet connection to get results?
Document: I researched a few of this products before deciding on this one. After a few weeks of use my swingbyte strap broke and the actual devise had a broken plastic tip. Emailed the company and within 20 minutes I had a prepaid shipping label to send off and get a replacement. Buy with confidence because this company's customer service is top notch.As for the device/companion app itself it is pretty easy and straightforward to use.
This is a lot of fun to use.The data appears accurate. I recently had a video lesson that showed many of the same issues highlighted by this device. I believe the use of this device and lessons is a powerful combination, you can get the feedback from a professional and monitor your improvement with the swingbyte.Two negatives that prevent this from being rated higher:  the strap broke after only 5 uses and it is hard to interpret the data without the help of a professional.
It has quickly become obvious where I am making mistakes. There are many features of the mobile app and website that are not mentioned in the product description. You can also use this to record putting, which I have found to be very helpful. I highly recommend this item and think that the price is an absolute steal.
Now that I've gotten used to it, I put up with it. I readjust it after every swing. Readjusting gets easier the more you use it. I don't even need the line because I sight down the two lights that are on top of it. Another Con: The swingbyte website uses Adobe Flash Player. The problem is that a lot of tablet and phone manufacturers are moving away from Flash Player. This doesn't mean the SwingByte people are archaic, but it's something that is plauging lots of websites.
I have noticed it happening on thin shots but not on fat or flushed one. You will have to realign it and  because you won&#8217;t be able to get it &#8220;exactly&#8221; where it was previously, you&#8217;re subsequent numbers will be slightly off for comparisons, but well within amateur limits. The instructions that come with the unit are very sparse and the website isn&#8217;t that good either.
So if you have an android tablet you should be fine here, I have no experience with the Apple version of the app.Some critical parts on this thing seem pretty cheaply built. I have hit around 150 balls with it clipped to the shafts of various clubs, and the plastic around the clip is already cracking. It has a 30 day return policy from Amazon and from the Swingbyte website, so I can't do that anymore, but the Swingbyte company has a 365 day warranty that I am trying to get.
This device provides good insight on your swing. It can be annoying at times when it loses the bluetooth connection, or having to recalibrate it over and over again, which interrupts your practice. My biggest disappointment it that it is very fragile. I sent it back the first month because the wire that hold the alignment line broke off. It broke off again, but I decided to live with it.
Hard to get on the club. When I tried to use it at the range the unit wouldn't sinc with my iphone.Gives you lots of numbers but doesn't tell you what those numbers mean. Looking elsewhere.
No slippage on either. Given that it uses rubber and pressure to stay gripped. I wonder how long this will last. I did find with a friend's club that if you have a sticker on your shaft where you affix the device, it will move.Connection:It connects via Bluetooth to an android phone or the iPad. I have used it on both. The iPad provides a nicer interface as the larger screen area allows it.Data:The amount of data you see is incredible.
I have a new iPad, with new software. I tried resetting the device, reloading the app, turning off the iPad and the same thing consistently happened, it would just disconnect the bluetooth connection at random. After 2 frustrating weeks of trying everything and getting on the blogs,  I returned it. In summary this is a nice idea, good (potential) data for improving your game but this thing just does not work. DO NOT WASTE YOUR MONEY ON IT.
