I have a refrigerator: for the drugs at a constant 7-10 ° and b: bought for my garter snakes which a hibernation with also 8 - need to keep 10 ° over 12 weeks chewed. Unit came quickly, and unlike many other ect without dents. on. Then leave according to the description first 6h and also switched according to the description at the highest level. frozen after only a short time complete refrigerator. !! all areas well below 0 °. Okay, then turned the temp knob back. According to the description yes to an adjustable range from + 8 ° -0 °. So the + 8 ° can not adjust it. I turn now to the regulator smallest level, so that that device turns straight. within 30 min. it is then cooled by 19 ° room temperature to about 5.2 ° men's. After the temp rises. Quickly brought back to about 7 ° then again to 5.2 °. Did the now repeatedly measured by a radio thermometer. After that I have in my 25 years !!! old privilege refrigerator measured. There you can still see the Temp. Reasonable rules and the fluctuations of max 0.5 ° take place in very much longer period.
Conclusion: The refrigerator is unable to reach the temperature of + 8 ° described, already at level 2 it goes into the minus range, has very large fluctuations within a short time indicating a very miserable isolation. For me therefore unsuitable.
