I have a Midea with 8C in the front and simultaneously -2C approx. 8 in. away near the back, so if not located properly, peptides will either be too warm or frozen. Temps will also fluctuate more since it is such a small space.
I didn't want a frig with a freezer, but I have one anyway, lol!
Whirlpool is probably as good as a small frig well get, so I might try that in a few months. Let me know if you start having problems with it.
