I recently purchased the Nuobell Dumbbells (awesome BTW) along with the single leg stand. The stand so far has been great, it’s quite sturdy, doesn’t take up a ton of space and seems to have to dumbbells spaced apart about perfectly for me.
Great purchase with the only drawback being the shipping charge when the dumbbells shipped for free. Being that they were shipped together that seemed a bit odd and kind of sneaky.
