Thanks for looking out bro, and while I am not familiar with this particular Vinotemp I do see two potential problems.
Whites go towards the bottom (colder) and the reds toward the top (warmer).
It seems as though there is no way to regulate the difference in temperature and that it is automatically colder at the bottom, and warmer at the top. That would make storing cigars relatively difficult considering the fact that you would never really have a constant temp.
The second problem, and the biggest of the two, is that it looks to be a condenser unit as opposed to the thermoelectric. When the unit is on and cooling it will effectively suck out the humidity which would make it a fairly pointless wineodor.
I point these out not to call you out, however to warn others about units like these, and to make sure you know everything there is to know about it before you buy it. If I am wrong on either of the two points above I apologize, this just seems to be the case with this particular model.
