Well built, been using it for an over a year. Strong water pressure. To prime the pump, hold open the spray head while pushing the pump down in the water, start the pump once it's fully submerged in the water. the recharging is not regulated, you have to watch the charging light and shut it off to prevent over charging. The charge lasts me a couple of weeks and takes around an hour and a half to charge. This pump is well suited to be used as a shower.
