In reply to Ben Curtis:
My wizard sleeve must be a slightly looser fit because it only takes me 5 seconds to put it on.
The fit isn't as precise as on the strapped Send but I find it good enough for 99% of kneebars without tape. It was my main kneepad for 5 or 6 years and I only resorted to tape for 2 routes in that time. Both times were for marginal technical kneebars after many moves of steep, 3D climbing.
Not having a strap makes it more comfortable, I can leave it on for a whole session. I have to wear shorts as it's too tight to fit over trousers.
For overall performance, I think the Send strapped is best. But if you consider value for money, I think the Wizard sleeve is a good option.
