My wife often says the Dyson v8 vacuum is the best purchase I have ever made, that was 8 years ago.
But for a cordless stick vacuum I do like the basic design. For real vacuuming I choose my Sebo E3 every time, but it's not nearly as quick to use as a cordless stick.
One of the best things you can do for a Dyson stick vacuum, in my humble opinion, is get an adapter so you can use something like a Milwaukee tool battery.
