+ Air flow ok
+ Pressure also OK
o smells really something to rubber, but as already described as extreme, I found it not
o No eye exists for a cord
o A dust filter on the intake valve would have been nice, but at the price I can not evaluate it as negative. I've summarily executed tinkering itself a filter (see picture). Just a lint-free cloth (often with cleaning kits for display / TFT's with it) properly fixed with a small cable ties ... and you're done. Filters at least the coarser dirt.
Power for the price a decent job, so my recommendation.
PS: For a little dirtier environments I was to take a look at the Super Rocket Giotto. This has eyelets for a collar and feet ... unless one is willing to spend three times for a bellows. I've had enough of this here :-)
However, if you plan to recreate the air filter, can also equal a cord with lashing.
