As for the Mesh itself: I am stunned by the quality of sound for such a small device! And I just try it, without putting her to the max because of recommendations to optimize the operation of speakers. The bass is very present and the sound seems to be able to climb high enough, enough sound to a room more than comfortable (and even better if you put gives the speaker against a wall).
The micro sd card reader works perfectly, the scope of the bluetooth seems more than adequate and the product finishing and very very good, it is not "cheap" at all, quite the contrary! I can not say about the battery life, but given the seriousness with which Adio Dynamics has demonstrated throughout the last month, I can only be confident and believe their word when they say that it holds easily 10 hours!
However, two minor drawbacks though: I had trouble pairing the speaker to my laptop (I had to change my bluetooth adapter, no worries by cons with my tablet and my phone) and I find that sound quality is much lower when using the cable jack ... but hey, I count mostly use the Bluetooth and micro sd card, so this is just a detail for me ... if not, not yet tested hands-free ...
In short, I can only recommend this product because of its sound quality, its presentation (highly successful packaging), its manufacturing quality, its price (I think to have such a sound, we should be closer to 100 euros with known brands), its service "before-during-after" sales ...
For those who doubt, I suggest you take a look to comments on amazon.co.uk and you will see that I am not alone in advising the Mesh!
