I have had mine for several years and it has not failed me. It does need to be maintained. If you use it for other than a car start it is watched enough to be a reminder. Very good for all around use.

I’ve used mine 3 times so far and the vehicles I used them on started immediately! I have one in both our vehicles and have given to other family members as gifts. Great useful product!

Great product used it on my vehicle and it started right up

Well packaged, using it as a back up battery for devices and portable jumper in the car. Luckily haven’t had to use the jumper portion yet. Back up battery is perfect. The casing is not too large that fits well in the car or to Cary with you and enough battery back up that lasts after heavy use.

This thing is the coolest thing I’ve ever owned. It started my Range Rover after it not being driven for 3 months in one try. Amazing tech! I love it
