The Good
Accurate gradient, user-friendly interface, touch screen input, tube support ring helps support even if you are using a few tubes
The Bad
Gradient running from bottom to top. Also, end of PCR is not indicated properly.
The Bottom Line
I have always liked the PCR machines by Bio-Rad, as well as a few other instruments made by them. This thermal cycler is always my first option when I am doing any PCR.
