Sure do - Probreeze 5000 that I bought from Amazon in the Spring of 2024. Best piece of kit I've purchased in years. Does it work? Yes. Is it noisy? Yes, but there's an easy fix for that that I'll describe in a minute.Are they expensive? No, not as long as you limit yourself to a 5000 or 7000 or 9000 BTU version. Mine is 5000 BTU and uses less electricity than a small portable 500W fan heater. What you need is a strategy to reduce noise and maximise comfort - for that I do the following. 1 - during the day I put it into the living room and cool that down - blinds and curtains closed and doors shut. 2 - at about 7pm move it into the bedroom and start cooling that - again doors shut and blinds and curtains closed. By 10pm the temperature will be down to about 16C and I go to bed. Turn off the AC (so now there's no noise) and just leave a small fan running all night. Keep the bedroom door shut and the curtains and blinds drawn and the windows closed. The same insulation that keeps the house warm in winter will now keep the house (the bedroom) cool in summer - just keep the doors and windows shut. By dawn the temperature will typically have risen from 16C to about 18C.
Got myself a ProBreeze a few weeks ago, and it's probably the best thing I've ever bought. I suffer from hyperhidrosis and heatwaves ramp up my symptoms to shit-hundred-and-fuck. Did you also get people saying "Wow that's super expensive! Is it even worth it?"
Not entirely sure what makes that worth £380... I have one made by ProBreeze which is almost identical which cost £200 during a sale on Amazon. For £380 I would expect a more powerful unit. I hate to say it but I think you could do a lot better for £380, or at least I would expect it to cost at least £100 less than it did.
