Not that bad, but it doesn't hold temperature very well. You might need a temperature gun so you dont over do it with the heat. It would still get the job done, if you know what you are doing.
This is a great peice of lab equipment. I would have to say one of my best lab purchases. Not sure why I waited so long to purchase. Saves time money and effort. Love it.
The temp control can be a little tricky to dial in, I use my infared thermometer to check the temp of the plate and make sure it stays constant before adjusting. The stirring feature works perfectly. An all around great value I'd recommend.
Great for many applications..use an infrared thermometer for best results in maintaining temps..feel around..it takes getting used to..but great unit..good price
