OK as a compatible but a niggle to note and not expect the branded quality
Ok this was bought for a Henry Numatic vacuum unit. However the pack is designed in its basic form to fit "standard: vacuum cleaners but is supplied with 3 plastic adaptors to allow the fitting onto the Numatic type vacuum cleaner. All well and good except when you try and stow the various tools into the predetermined holders on the back of the vacuum you can't do this with the attached adaptors still on. They simply don't fit on SO... you have to remove the adapters each time but there's nowhere to put these on the Numatic. Nuisance and a niggle. So you have to keep the adaptors somewhere else (where they can be lost/mislaid).
Apart from that the set is low cost but time will tell if the cheaper plastic used will stand the test of time. We shall see. In deciding if the kit is "good quality" I've answered "no" but then it's what you paid for and so it's what you get. If I'd been prepared to pay the higher price for the branded product then of course no contest. So for the price paid the quality is "acceptable". Don't expect superb quality when you're not paying for the real McCoy.
