The hose was initially so long that unfortunately Lot very often got stuck in the tube and I brought out there difficult. After I had cut him, ejecting the solder work mostly, but it stuck sometimes anyway, so you had to pull it out by hand. So here again you can not expect miracles. Probably, it is hardly possible to construct the pump so that the solder is really getting thrown out reliably. But of course it also depends on the amount extracted.
The suction power is really good. The silicone tube can be well put on the solder joints and seals the edges reliably.
As long as the front remained hanging no Lot I was able to work very quickly.
Overall, the pump is mainly simply a higher-quality alternative than cheap plastic pumps and is accordingly also better in the hand.
The suction power is very good. Otherwise, they do their job as it should be for a desoldering pump.
