Bests & Worsts Reviews from Amazon

IMU could not calibrate. Firmware update failed. Had to send back for repair. The tech support leaves a LOT to be desired. Update: Their tech support is probably the most incompetent I have ever encountered. Hope and pray your unit never has a problem. First, prepare for hours of wait for tech support. There is no call back. You just have to tough it out. When you finally get through, be prepared to talk with someone who only understands very basic English. They have scripts they desperately try to keep within. If you ask something that it not specifically on their script, they try to force you back by not answering your question. So really LISTEN to what they say and keep repeating your question. Eventually (typically 4-6 times of repeating the question), they will go ask someone (takes a long time every time). Whether you get an actual answer eventually is a crap shoot. For my unit, which was shipped with a defective IMU, I finally (after three calls with hours on each) got them to accept responsibility and fix it. They told me 10 days turn around. We are now coming up on 3 weeks and I finally got a shipping notice that it will be here on the 4 week anniversary. That's pretty upsetting because I called them and told them I bought the unit for my European vacation which I am leaving for on the 13th. I told them if I could at least expedite the shipping back using priority rather than the regular ground they use to save money. After two hours of discussion they told me the shipping notification from them MIGHT would have a link to request expedited shipping. It did not and they shipped it ground. As a result, I will not have it on my trip which I purchased it for. Unhappy? You bet. For a $1,200 product one should expect SOME competence in tech support.
