The so-called manual is not very good, nor complete. The build quality, however, is quite good with a metal cabinet and few plastic parts. The form factor is perhaps larger than other comparable products.The temperature control is also pretty accurate. The heating plate is very effective (500 W), so there may be some fluctuations until it settles at the right temperature (hysteresis). I have checked the temperature control against two precision metal thermometers. It is possible to dial in an offset value (+/- 9.9 degrees C), but I haven't needed to do so.I have noted the lack of insulation of the electrical heating element contact points, but I don't think that poses a problem with normal use.The stirring function is very effective.Delivery was also fast.However, when I ordered, I got cold feet after 15 minutes because of the many negative reviews and tried to cancel the order. That was not possible, and that irritated me quite a bit. Luckily, the product is better than I expected.
