A couple of weeks ago I bought one from
here on Ebay and I'm very pleased. It's done about four wheels on/off on a single charge, but comes with a 1hr charger and a second battery. I plumped for the 18pce socket set too, they were out of stock of the one mentioned so sent me an 18pce Rolson set instead. Not the best quality perhaps but seems plenty adequate for what I'm doing with it.
Last week my car failed the MOT for cuts to the sidewall of one tyre, so Mr MOT advised me to fit the spare. Didn't I look like the coolest guy in school when I jacked it up on his forecourt, blitzed the wheel off and fitted the spare? I re-presented it for test 5 mins after receiving the failure sheet, and it passed

It wouldn't take very long to re-fit the allegedly dangerous tyre that evening either, but I wouldn't know about that. You're welcome to borrow it for a week to trial it if you like?
