When they work they’re a nice gadget. Within a minute you can see whether your scrubber is working or not. However, they fail fairly quickly. I replaced them two times and after about 30-40 dives they start failing during the dive. So I started using them only during pre-breathing and disabled them before the dive. But after a while they failed completely. I won’t replace them again and do my 5-10 minutes pre-breathing.
