Not massively helpful as they only do them on specials but keep an eye out on Aldi car specials. I got one when they had them a couple of years ago, it was £25 which was much cheaper than others of that spec at the time and it's brilliant. It does everything from my bike tyres to trailer tyres although we only ran ours at 60psi. This was a rechargeable battery one as well as 12v
Get an Aldi one, they are fab. When mine was sadly lost when my car was written off I hurriedly replaced it with an RAC branded one from a supermarket. It is rubbish, don't bother.
