The Good
The presets make it extremely easy to click start for whatever type of cell you want to spin
The Bad
The alarm that rings when the spinning is done is quite soft therefor you will need to check on it to know whether its done spinning
The Bottom Line
This centrifuge has been working for us for many years now and there has been no problems. We have not had any type of services done ever since we purchased therefor the quality is one of the best
