Negative I noticed the one hand that the plastic edges (when the two purchased from me keepers) were very sharp (ie non-burred), so I cut to it. You could even file off if necessary, however. Secondly, the LaPlaya Active Sports Aluminium Sport and bike bottle 1.0 L has been very badly scratched by the bracket. Whether this was due to a lack of quality of the bottle or on the sharp / rigid support, I did not want to try a SIGG bottle prefer.
Finally, I had the second SKS bottle holder is a problem that I could not use him on the seat tube on my mountain bike. This was because the two holes are quite far down and the SKS bottle holder (unlike my Noname Metal Holder) "offset" slightly downwards. A bottle would be put directly on the down tube with this assembly and would therefore not be fully secured in the holder.
Quick Tour (+ good | neutral or occasionally relevant, - worst):
+ Stable, robust
+ Low
| Very tight / stiff
| No hexagonal case
| May (always) damage to the bottles
| Mounting on the seat tube may not be useful
- Not deburred
The bottle damage, the lack of deburring and to narrow / rigid opening lead for me to devaluation.
