Got mine from Amazon and used numbers of times. Only time it didn't work was when I tired to jump an old suburban. Don't think it was the jump packs fault since I couldn't even jump the burban with my truck running.

Very happy with my XP10; had used it only to troubleshoot 12v circuits (lights) from time to time after the initial charge. A few months later was picking folks up at the airport and saw the family across from me in the lot with the hood up staring at a dead battery. I pulled it out just to give it a shot before popping my own hood and grabbing my cables-much to my surprised and definitely to theirs, it plugged in an fired the van right up.
It's a good product. If you want to the hookup pig tail on the battery for quick connect bear in mind that isn't an XP10 compatible accessory.

When I spoke with Anti-Gravity in June, they had a "bigger better" unit on the way. Their web site is a mess, so may be smart to call them if you are interested in something bigger than the XP-10.XP 10 is the strongest of these and probably the best one to pick.
I purchased mine back in March 2014 on Amazon from Lytle Racing and paid $138. If Antigravity is not backing up their product purchased from Amazon it is complete BS and no one should purchase product from Antigravity.
I asked them about this before purchasing and they were adamant that they do not sell via Amazon and none of their authorized distributors do either. They suggested these were 'seconds' or refurbished products and would not stand behind them. I emailed a few of the Amazon sellers and they were equally adamant they were authorized re-sellers. So who knows. I bought direct to avoid the hassle.
