I’m using a uni connector to hold a Sonos Roam portable speaker, and this mount works perfectly to hold it in place on bumpy city roads. The straps and base are grippy and hold surprisingly well!
The cage piece is great but the straps are not very good. The straps that come with this are unsightly and not very secure so my bottle would move a bit on every ride. I found some new straps online (nano straps by Voile) that made this perfect - looks clean and is now very secure.
Clean well thought out design which is highly functional, as advertised
