Our Lab purchased this item few years ago. I have it in my personal use for 2 years. I was freezing with this unit iPSC, hESC, monkey iPS, isolated monkey CD34+ for BMT, MSC with relatively successful rate 70-95%% with DMSO. Recovery time to bring it to RT for reusing not 5 min, but around 1 hr . Freezing time practically 2 hrs in environment at -80C. Its convenient no need to refill with isoplopanol, taking in account price ~$85 plus endless usage - good deal.
