Cool Yep, not really new though. Guys have been using these at our track for a few yrs now. They work really good, just a little noisy though. About the same loudness as others when their using the track air compressor I would say.
They've been around for a few years, as I've seen them trackside on a few pit tables. I'd buy one, but I carry around enough gear as it is. So long as an air compressor is available for use at the track, I'll use it - otherwise, it's a great alternative.
