I love the product but it took quite some time for vendor to ship it.
The heater is very compact, heats up fast and the plate is smooth and rigid. The only possible downside is thst the actual temperature display is not cotrect at lower temperature. For example, if I set the tempetature to 37 C it heats up and shows 37 C as the actual reading, but if I measure the plate temperature using a high quality kerosine lab termometer (with a wet cloth between the plate and the bulb to ensure good thermal contact) it shows 44 C. Well the 7 degrees error is something to be improved in the next revision. But the temperature stability is good so I can make some adjustments and be happy with the product. I suppose the usage at lower temperstures was not the main purpose of the product.
