content: I bought this little desoldering bulb from Canadian tire:http://www.canadiantire.ca/en/pdp/weller-de-soldering-bulb-0580006p.htmlbut, the hole is very tiny, compared to the pumps, should I drill a bigger hole? Also, how do I empty these things? I cant seem to get the tip off.

content: Those bulbs are useless. They suck far too slowly. You need a spring operated piston pump. Even some of those can be pretty hopeless, but a GOOD piston pump is an excellent cheap and compact desoldering tool.

content: I'll second stj, I have one very similar and it does work well.I can't really believe that is sold as a desoldering tool.Reminds me of the little air pump very similar I use to bowl off my sensor on my dslr.

content: How does something from a reputable brand like weller get out classed by some chinese made "crap"?To its credit, it did work pretty well on some joints, not so much on the smaller joints.

content: Definitely use the silicone sleeve. It confirms to the joint/iron tip much better, giving better suction. If you have a hobby shop near, just stop in and grab some silicone fuel tubing for gas powered R/C model engines. A pack of this tubing is cheap and will give you enough to last forever.

content: In my opinion, the best desoldering handtool is still the original EDSYN SOLDAPULLT III PT409 or DS017LS.http://www.edsyn.com/category/DHT.htmlThere are crap chineses copies of DS17, but nothing to do with the original EDSYN one.

content: In 1973, I have buyed 2 PT109 EDSYN and I used them up to recently.I only had to change the tip from time to time.As they are now well worn and one of them has a broken spring, I recently buyed two new ones.I don't know if it is EDSYN, HAKKO ou other who own the patent of this desoldering handtools, but at least EDSYN PT109 exist for a very long time ago. (well before 1973 !)
