If this thing is a copy of anything it is a copy of a tunze not a vortech. The mp40 is wireless and the motor is outside the tank, this jebo is mounted inside the tank and does not discuss wireless networking. I doubt it is comparable to an mp40 but it still seems like a decent buy for the price, assuming it lasts longer than a hydor which seems to have a similar build. I have used tunze, hydor, and vortech powerheads and the quality and flow pattern of a vortech is unmatched...tunze are nice but completely different more like a lazer beam (granted I have never tried the new wide flow model). The non aim ability of the mp40 is a nonfactor as it creates flow all over the tank, you have to see it to understand. I think I will buy one or two of these as backups and maybe do a side by side comparison of it with the other powerheads I have. Like I said before, this seems to be a good buy for the price point. The product description is a little hard to read though. I don't think people selling vortechs because there is something wrong with them, rather they just don't need them...otherwise there would be what ever is wrong with them listed in the sale (at least for a responsible seller and I can't imagine every perso selling them is dishonest). I rather believe you see more vortechs for sale, then say hydors, is simply because the vortechs last longer than the others making more available for sale when the aquarists breaks down or has no need for it.
