I got mine today! I'll do a quick first impression/unboxing review right away:
The first thing I notice is that one of bottles has leaked a bit. How this is possible, I have no idea, the others were 100% intact and with the childproofing and all, leaking just shouldn't happen. Either way, one bottle leaked a few drops in the box and made a mess of its stopper. No big deal, just slightly annoying. Might be fixable with packaging that makes it impossible for the boxes to move around.
This aside, everything looks swell. The stoppers are great, the childproofing is effective without being inconvenient. The size is consistent with other major brands, which makes for good storage. I really like the names/designations of color and 'strength' - makes it really easy to know whats what. Even if you go with more flavourful names, please keep this.
All it all, they look nice. I look forward to trying them out, I'll write more once I've used them a bit.
