I have to agree , although I use them myself , but for sanitising and biological remedial work. They are the only cleaner I found that can be stripped down for proper cleaning between jobs, which you will not need for ordinary work. The bigger ones are of course better but tend to retain horrid things and smells in their dank depths and the thought of having to scrap a couple of grands worth of machine because of a failed swab test eekk. The Kiam is also good for adaptating, for small scale work.
But a good start up tool with a guarantee.
