The pressure is very weak and the reservoir doesn’t hold a lot of water.

While the device appears sturdy and well built, the reservoir is a negative. On the highest pressure setting, the reservoir will empty quickly, and you'll need to refill to continue the process. Recharge time is fast, the recharge "band" is weird, but works.
