Great little pump. Works well. But the little red plunger handle on top is very then and brittle. Mine disintegrated with in minutes of it's first use. Still I highly recommend this tool. It has cut my water usage down a lot and I think with it and the drill guide they have cut my drilling time down a lot. I'll drill up to hundred 1/4" or 5'16" holes in tile on a pair of public restrooms for stall partitions and accessories. These two tools are perfect for the job. Really beats starting a hole by holding the bit at an angle and having the bit skate across the wall. While you are trying to use a spray bottle (or drink bottle with a hole in the cap) to wet the bit.
