This seemed like a durable replacement pump for pumping a bleach solution, but on its first use the handle broke right off.The pump itself was not smooth at all which probably contributed to the handle breaking, but I expected much more from this thing. Happy I bought a spare that typically lasts about 12 mo before the bleach seems to degrade the internal mechanism even with rinsing after each use.
