I like it, received as Xmas present three years ago.  Fits the top of all my 5gal plastic buckets.  Ports fit all my misc collection of 2-1/2inch hoses and adaptors.  Eliminates the heavy clean-up mess from my saw.  Much easier to dump and clean than my wet-dry vac.  Vac filters and dust bags last longer.  A great start towards a more complete dust collection system.
