Has anyone ordered from them or had any experience with refurb'd dosage pumps. They seem to fit my needs pretty well, but I haven't heard of anyone using them.
funny you should ask because i just got one for my new tank. i tested it and it works great. quiet and pretty easy to use. the pumps are a little big but if you have room this is a good alternate to reefkeeping ones that costs much more. i got mine off ebay but i have talked to don before and he is a nice guy.
