I have no experience with this brand in particular, but I do have some with chinese lights. Some are good, some not so much... I went with a bunch of Xtar (a Chinese brand) d26 2500 based on previous experience with their chargers, and pretty decent reviews from other members. Purchased 5 on Alibaba with wholesale pricing, and have been pretty happy with them. Xtar is also active on this board, and very responsive to questions, complaints, etc... The best part is they listen to our suggestions, for example, bringing back the mechanical lock on some of their models. That was based on our requests...
My advice is to give it a shot, but stick to the more established brands. In the grand scheme of things in diving, the cost of these budget lights is minimal, especially if ordering direct from overseas; even more so if you buy a few wholesale with some dive buddies. It is certainly possible to get very good value for your dollar if you do your homework. I'd check out the offerings from Xtar or Orcatorch...
edit.... just did a search, and apparently wurkkos is an offshoot of Sofirn lights. I have a couple of their lights, and found them to be well built for the money. I've got a couple SD 02 lights that have survived to 100 ffw and didn't leak. Excellent value for something g like $30 shipped. Give the Wurkkos a shot and report back...
