Don't stay away so quickly just because of a couple of reviews... the BCD is sold-out and seems to be a huge success.Thanks for your review. I'll stay away from it then.
When I bought my Hydros Pro, some reviewers were crapping all over it. The BC is AMAZING, love it!
Like with everything, some people like it, some don't. The complains above are very personal... the chest strap for example, only needs to be clamped on the surface (unless entangled UW). No big deal at all and a metal hook is much more resistant than the traditional plastic clip.
The bottle moving, well I haven't tried it BUT it can also be that the OP was used to traditional BCs or BCs with a taller rubber tank holder instead of just the cinches so that might give the impression the bottle is moving. Any travel BC with a soft back gives a similar feeling...
IMO, if you can find the BC and you like it, buy it and try it! IMO not only it looks great (especially the Orange) but Apeks knows how to make TEC BCs so this should be a solid choice
