We bought this to act as a cooler for a heated vacuum pump and it's doing that job well; the water temp is staying constant at ~34c as opposed to >100c or low enough we start getting condensation. Not quite what it's designed for, but it's doing it, and its cheap enough to replace as needed. We had some issues getting it delivered (delivery company held onto it due to import taxes for goods from the EU, but didn't tell us, hooray Brexit), but this was rectified quickly with contact to the seller, who even paid the taxes!
