Quality Milton pumps, I've had no problems with mine at work for several years when I bought a new one. However, I bought this "used" for the home and was very disappointed. First they sent me an inflator with a 6" double ended which isn't much but it's not what I ordered. Second, when I wanted to use it, it dripped like a strainer from the swivel at the end of the hose. 100% my fault for missing the return deadline but disappointing nonetheless. I need to get a new hose for that. I would buy this product but recommend staying away from the used version as I don't consider a very audible air leak to be "cosmetic damage".
