Hydromatic cartridge filters

[gd5015]

Anyone know anything about these cartridge filters? As far as I can tell, they are manufactured by the same company that makes Pentair. What, if any, problems would I need to watch for, especially at this price? They also seem to be called Sparco Hydromatic or just Hydro.

There really isn't much to cartridge filters, the only thing that can really break on them is the o-ring and maybe the drain plugs. So basically what I would watch out for is the price of the replacement filtering element, price and availability of replacement parts like o-rings etc. That's basically it I'd say. If you like the price go for it.
