I bought this accessory because it has brackets that can be screwed onto the wall to support wings that hold various Dyson suction devices. What is wrong with this product is that there is not enough room in the hose holders to remove Dyson hoses and fittings without wiggling and tugging on the suction fittings to pull them in or out. The alignment slots are too narrow. The Dyson LANMU faucet holder (another brand also featured in Revain) is a dream when it comes to removing and installing accessories. LANMU doesn't have brackets that make it more stable, so it's a bit more shaky.
