Bests & Worsts Reviews from Amazon

the FAKE 1/2 Star --- the REAL XP-10 5 STARS PLUS This product, purchased from Shun Tech, UNFORTUNATELY, is a FAKE. It does look good and works initially as it should and costs less than the real thing. However, after 2 uses, it already has shown a decrease in performance. The copiers know to fake and it can easily fool anyone without the benefit of a comparison. It is being returned to Amazon for a full refund. I have been in touch with the the genuine manufacturer, Antigravity Batteries, and they explained the subtle differences on the outside of the battery and packaging. The real problem is what is hidden inside from this knockoff that can one day fail and damage your vehicle or laptop. They use cheap and of unknown quality components that if they fail at the wrong time, can cause a problem that will leave the user with little recourse. The most obvious difference between the real battery and the copy is the outside finish. The copy is glossy, looks good, but is slippery and just the first of compromises that lurk in this knockoff. The real XP 10 is covered with a rubberized finish that before you buy from anyone except Antigravity Batteries, you should make sure that this is what you are getting. Do not want to suggest that Amazon, Shun Tech, or any of the other sellers knew that this was a phony. But they should know now and remove these fakes from the marketplace. Will buy this directly from Antigravity Batteries, and I urge you to contact them and see what they can do for you from a price standpoint. This way, you will get the real quality you are paying for with no surprises down the road. [...]Update: March 2017 After using for over a year to jump start my car's now weak battery and to power my laptop while on the go, can attest it is reliable and gives OUTSTANDING results.
