Bests & Worsts Reviews from Amazon

After 5 years and 2 months of use...maintainng motor cycle (small battery). I needed to use it on a full sized battery... I press the mode button and it does nothing, press a few more time and it goes into standy mode and never comes out again. try to hook to no battery/good battery/bad battery ...no difference. Stuck in Standby mode. So I dont know when the mode cycling feature failed. btw, to use warranty you need to pay for shipping, and after 2.5 years 35% of the cost of the product..... Since I was not going to returnit I opened up the unit and found one of the worst soldering jobs ever. The outside if the unit is very pretty the inside very poorly soldered ..... I found a cut terminal lead loose/lightly tacked onto motherboard near the mode button. With the quality of the soldering of this unit, I would not call it ulta-safe.....
