Holds temperatures very well, +/- 0.5 C. Tests for temperature statification show minimal gradients. Draws little power; I have three on same circuit. Vary good value esp if purchased used as I have. Brand New prices high for what you get.
Works well but watch actual vs setpoint temperatures and gradients
Th incubator works well and can rapidly reach stable temperature. I dd have to calibrate the incubator against a calibrated thermometer because atevery temperature actul differs from setpoint by 1-2 dgrees C. No biggie. There ar horizontal and vrtical gradients withi the incubator, with highest uoppr left and lowet lower right, total gradient 2-3 degrees C. Part of this due to the warm air coming from vents in top. Ovrall serves my needs as a microbiological incubator
