I purchased this in July last year, as in the main, the reviews seemed to be OK. I only used it on a couple of occasions and it was great - it worked much quicker that the old inflator I had used previously.
As the car has been idle for a couple of months, I needed to inflate all four tyres so yesterday, I used it for the first time this year. They wearn't flat but were all low, about 18 - 24Lbs. All progressed OK to start with but it was slowing-down by the time I started the third tyre; it had about 18lbs and needed to be at 32lbs..
Well, it never got there - the compressor got slower and slower, so quickly decided to switch it off but before I had the chance to do this, it just stopped. There was no power (the display was not illuminated) so decided to check the lead. As I opened the door, I was greeted with that horrible smell of electrical burning. The plug had partially melted and the fuse had blown. So I chopped it off and replaced the plug with a much better quality unit and nothing; I checked the polarity and that was fine as there was power gitting to the unit as the display was now lit, so it was clear - the compressor had seized.
So, used on three occasions and that's that! All I can advise is to beware - this, and I have to guess the all the other rebaged clones such as Ring, Streetwise - must come out of the same chinese factory. Its a very cheap product, but there is a reason - its awful. Frankly, the AA should be ashamed of the licence fee thay're collecting by putting their name on it.
