Never used this product before but i always stayed away from Internal compact units. Check to see if replacement parts are readily available (impeller, waste cup, etc) and wont cost an arm and a leg!!!lol
I would like to stay with reputable manufacturers with whom replacements parts are readily available even if they cost an arm and a leg.
Look into Seaclone, although their coupling mechanism are not that great but for the money, I think it's worth it.
I do not know how good you are w/ tools. You can modify waste cup of
HOB (drill holes to apply hose nipple) in a way so that waste can collect in larger Waste Collector (
DIY using
PVC, and ping pong ball) thus no need to worry water water on the floor.
