Re: Do NOT buy Nammor.
I have 6 nammor's now.. first one the plug in part snapped, but that was cause a friend of mine dropped it. Three of them have had no trouble. 1 the hose came out of the handle cause another friend was swinging it around by the hose, and generally mistreating it(ive told him to stop being a moron since then). The sixth someone crushed the handle piece's interior pipe by stepping on it, but thats not too big a deal, it works okay.
All six still work, They've all been easily fixed(save the crushed pipe one, no way to fix) with super-glue, the breaks have been stuff that I would call above and beyond normal wear and tear.
All of them still function just fine.
