Review on 🔧 Aven 17535 Desoldering Pump: Unlock Precision with Locking Plunger! by David Thomley

I used it to replace some components on the radio board. He did his job excellently. It is mainly made of plastic with a metal spring and shaft. When the pump is turned on, a metal rod passes through the inlet, effectively cleaning it of solder after the last suction, and then retracts slightly so that it is not visible during use. so it doesn't cut or pinch your fingers. I wouldn't call this tool "heavy duty" and wouldn't recommend it for "everyday" use. But it does its job well and is durable enough for repeated use.
