H2o Blue Pump

Pump With Water or Air, Your Choice

Waterproof and built for the bath, the Nasstoys H2O Blue Pump works two ways. Fill the cylinder with water in the bath or shower, insert, and start the pumping sequence. Out of the water, it runs as a traditional air pump. Water fills the space around the shaft, so suction spreads evenly along its length instead of concentrating at one point. Warm water adds a soothing feel to the whole session.

How It Feels and Fits

The cylinder is ABS plastic, 11.5 inches long with a 2.8-inch diameter and 8.25-inch circumference. It's fully see-through, so you can watch the shaft fill the chamber, and a measuring gauge is built right into the cylinder. Nasstoys recommends it for users up to about 7 inches long and 1.8 inches in diameter when fully erect, which leaves plenty of room inside.

A good seal matters with any penis pump. Three silicone sleeves come in the box: small (1 inch), medium (1.25 inches) and large (1.5 inches). Pick the one that hugs the base snugly and the suction holds steady. The soft silicone feels gentle against skin.

Power & Performance

This is a rechargeable pump. A full charge takes 60 minutes, and the working time is listed as 50 uses. It runs on 3.7V and is whisper quiet, so it stays discreet in a tiled bathroom. Weighing 1.1 pounds, it feels solid in the hand without being awkward to hold.
