MTB252 and MTB162 hubs from bikhubstore, anyone try them?

[JMT]

I am going to build a new pair of wheels but I haven't decided on the hubs yet. The Bikehubstore hubs MTB252 and MTB162 have a very good price, are light and to my understanding quiet (if noise was OK I'd have gotten Hope hubs). What I don't know is how well sealed they are. I don't want to have to change bearings every month. I am not going to ride in deep water but I do tend to ride in somewhat wet environments. Tey'll be used for winter riding in snow as well. Has anyone ridden these hubs for some time? How do they stand up to other hubs?
I did look at the Rotaz hubs as well but I saw some reports that said the seals were not that good.
