Yup, this torch is very durable and very bright. Simple design, 3 o-ring seal, and it's comparatively brighter than most backup torches I've encountered. And best of all, it is so cheap.
My complain is similar to snikrs. The plastic battery holders are a bit flimsy in design. I did not have a problem with the holder itself, but the solder from one of the springs came loose. Luckily it is easily fixed. Also, the vendor does sell spares if you need them.
Main complain though is the weight. They are quite heavy.
