These tools are perfect for my Dyson. I wanted something I could use to vacuum crevices and corners, car seats, furniture (without scratching it) and a few other obscure areas, and these tools did the job. , and all around. The long T-shaped nozzle with velvety soft lining is ideal for cleaning electronics, hard surfaces and more without scratching them. Very often two are used with sliding brushes. My Dyson comes with what looks like a smaller one so it's a good backup if it breaks. I like the wand attachment with the brush on it as it prevents the vacuum from sucking on the cushions when I'm trying to get all the debris out of the crevices of my leather sofa. . Although it works, it has too many holes in my opinion. It's designed to suck at the pad and along all the brushes, but you end up with less vacuum and more brush as there's more suction loss due to the large area. But the flexibility is good for getting into shelves, behind consoles, etc, so it's not a total failure. Overall I would recommend this if you have a Dyson, it's a great addition to an amazing vacuum.
