The equipment is doing great. It works as advertised. I use it externally with a Water-Jacketted Vessel, to maintain a constant temperature. I always have the need to protect the integrity of the heat sensitive ingredients I use for Skin and Hair care Formulation.

I have been using this thermostat for about a week. I am not pushing it to the limits, just keeping it at a stable 20°C with a small amount (about 5 to 10%) of ethylene glycol added mainly as a disinfectant (not so much as an antifreeze). I rated its "quality" four stars for now because I still need to see how it performs over time. If it runs well for at least a year, I will update my rating to five stars. The price is very reasonable, and I agree with the previous reviewer on that point. However, long-term reliability is what really matters. These devices are normally expected to run continuously for years. I use six of them in parallel at different temperatures, although this is my first time buying from this manufacturer. Over the last fourteen years, I have replaced eight units, but two or at least one of the original units are still working.

Works extremely well. Can easily go from chilling to heating which is especially useful for jacketed reaction systems. Go flow pressure. Great for the price especially.
