I like that the uni base let's me add a 2nd water bottle for the summer and the mount isn't too visible when not being used and the magnetic attachment is pretty cool
That said the bottles themselves feel a bit thin and aren't the easiest to get a fast drink from but I haven't had any issues yet
The mounting straps could be improved they don't really lay flat and they're very long it wouldn't really be an issue if the price point were lower but for a $65 water bottle the straps aren't impressive since there's various options for $20 or less to strap another water bottle mount to your frame

I would love to give a positive review, but I haven't received the items yet. I look forward to trying out these twist bottles.

I used this to mount a bottle to the top tube of my gravel bike so I could carry more water on long rides. It works great and allowed me to ditch my hydration pack. You can probably mount this anywhere if you need to add more bottles for big days - like putting two on your fork.
