I didn’t received my package. AliExpress force the seller to give me full refund. Thx to AliExpress.
the tool is not so powerful as described, the batteries are in a very low quality! one of the two is completely out of order after the first discharge, and the charger is really kind of a jock.
shitty batteries, it will not work for you more then on charging cycle. do yourself a favour and save your money. (and NO, they will ignore your claims, and it is impossible to prove that the batteries can't hold charge with photos...so AE will ignore you as well...).
