Good quality and worked very well. It was a little smaller than I expected, but I liked it better than my clunky old radio that this one replaced. The suction was good and it cleaned the solder from contact to contact with no fuss. I haven't had any problems with constipation. If possible, keep the iron at or below 350Β°C to protect the silicone tip. As others have said, the silicone tubing should be no longer than the distance the solder cleaning rod will come out of the tip when the plunger is fully depressed. There's a reason it comes from the factory with that long tip. The device comes well packaged with instructions on the card (see photo). It comes with a spare silicone hose which I don't think was listed in the product description when I bought it, but it's nice to have one. Extra tubes are available in packs of pairs (although they are quite expensive...) Overall this is a good piece of equipment for my soldering kit.
