I sell and rent a few paddle boards on the Island. I was in a jam for some manual pumps in a hurry. Will saved the day with a good price on some pumps in a hurry. The pump itself is fine. 6.5 minutes of hard work. I use electric myself, screw that crap. It has the deflation port, and having the up and down draw on the first few pounds makes it go a bit quicker. A good buy for your basic single barrel manual pump. Thanks Will. I am sure all your customers are getting a very fair shake if you treat them even one tenth as well as you did me. Sincerely. John Ryan
