Misconstruction because speakers on the back

The children of Pedi Tablet Odys Because I'm (still the old version with a Processor) and very satisfied with, I thought I can not go wrong when I come back to buy myself a tablet of Odys.
Basically, it is also true. The tablet works quite well, and I have the same good WiFi reception as the Pedi (briefly times had the HP Slate 7 Plus for comparison Odys still had reception where HP had to fit).

But:
When the speakers are mounted above Pedi on the side, will never obscured. The Pedi also has a volume control.
Whoever comes up with the idea to bring a device without volume control on the market and to attach the speakers to the back of these days? Odys ..... Total misconstruction. Many tablets have the speaker on the back, but then wenigstes so attached that they are not completely hidden if the tablet is flat on the table ...

Otherwise the Opos is no longer the bearer of what it was like the Pedi. It is heavier than the Pedi and the casing does not feel so good like the Pedi. I would even say it feels cheap ...

Here I can not give buy rating and have the Opos returned.
