I think is shows the "Infamous" DSD charger is relatively a good one, especially for the price, while keeping in mind it's slowness in getting the job done; but safely.
Keeping in mind it really is only a single channel charger and only uses the Constant Current method at the transformers rated output (~450mAh) to ~4.25V, followed by true charge termination; no trickle charge, and that's good.
It does not switch from CC to CV (Constant Voltage) @ 4.20V, this makes it a cheap charger BUT test yours out with a DMM because I own 4 of these and all 4 of them are at 4.20v during the entire charger process; so really for the money it's hard to beat this one and is relatively a safe charger.
Some have reported their DSD's have charged their batteries to above 4.25v NOT good, so again you'll to test each one to be sure, China quality can vary on this product. I usually test every single battery coming off the charger and have good luck with this not ever going beyond 4.20v they range 4.17 - 4.20v
Reading through some of the others on that thread is scary.
I'd still recommend the Pila if you don't mind spending the money because it follows most Li-Ion manufactures charge recommendations for their 18650 cells to a "T".
Additional info:
I found a site in Germany that has a lot of info on these;

Also a site in Italy showing a True 3000mAh 18650

What I learned from the German site is there is apparently another charger out there that is really good and follows the CC/CV rules.
The surprising part is the company selling it is in the USA and the price $14.50, they even have a test graph on their site and you can also purchase a car adapter for it.
