I had bought one of these kits my first time probably about 4 years ago ago. I had never really tried to use the electric impact “thing” not exactly sure what to call it lol. At first I thought it just wasn’t working right. And then I thought it was just broken. Til I finally gave it a REAL try. WOW! The impact gun thing is next level amazing. I dunno who invented this and not sure exactly how it works. But if u have a stuck bolt you just CANNOT SEAM TO GRT OT OFF OF YOUR WHEEL, THIS BABY WILL DO IT WITH EASE! No joke. It’ll wind up, then “ clink” …..”clink”….. “clink” as it winds up each time it’ll take one smack at the lug, winds up again, another smack at it, and so on. You really gotta pay attention to what it’s doing to know it’s working. Cuz my first few times I tried it out i just assumed it wasn’t working correctly. But ohhhh man does it!! I promise this thing is next level amazing ive had a few other stubborn bolts over the past few years that I’ll show a friend and say “watch this” and then they can’t believe what this thing does!! The jack itself, it’s OK for the money. Every one Ive purchased only lasted a month or two of decent usage and then it all started to fall apart. Diff small things would break or need re wired. But once I purchased (now my :rd) I know to take better care of it as I put it away after usage. I put the gloves it comes with over the remote to protect it so it doesn’t get all broke and cracked up. Just a few little pointers for any first time Possible buyers to make your purchase last longer. These are what they are. Cant expect some AMAZING thing for this kinda price. If you have minimal usage, these are nice. But I tend to use mine quite often and these just aren’t for that. Cheap parts and they break easily. Every 3 ton ive gotten the inside wheel has chipped and broken all 3 within 2-3 months. But hey, for the price, Im still happy! Just a little let down. But VEVOR is amazing and I buy tons of their stuff as it’s ALWAYS the b
