The pump itself isn't spectacular, but it's still a good value at the price. The two weaknesses that I've experienced with this pump are the hose connection to the board, it can be a bit leaky, and the umbrella valves built into the pump are prone to unseating. Let me explain the valves. There are two, simple one-way rubber valves to prevent blow back as the pressure builds in the inflatable, one is easily accessible under the pressure gauge directly behind where the hose connects, but the other is fairly inaccessible and located inside of the bottom of the pump piston. If they fail, you are likely to find them wedged somewhere inside of the hose. The top valve is fairly easy to reinstall, but due to its location and construction of the pump, the bottom valve would be challenging if not impossible to replace. The pump will work with only the top valve in place, but be aware that if both valves fail, and when the inflatable is reaching pressure, that there will be substantial blow back of the pump handle on the backstroke. All of that being said, the customer service at Tower is top-notch. I recently ordered one of these pumps, had a problem with the hose, and was immediately issued a replacement at no cost. Thanks, Tower, keep up the good work!
