Austin B. (Washington, United States)
Great autoclave for the best price I could find.

I bought this as a replacement for my previous Midmark. I was angry about having to spend so much money on an autoclave but was able to find this affordable option. They offered the same standard 1 year warranty and offered a 1 year extension that my dental supplier did not even offer. It took 2 ish weeks for delivery and arrived when the tracking said it would. I would buy from here again if I need to.
