Challenge - MPS2-08CRN1-QB6G1 8000BTU Portable Air Conditioner

I've got a Challenge 8000 BTU. Not sure the specific model is sold still (it's a bit old now). It's loud, but sure as shit it works great. Kept my room at 17-20c when we were in the 40s. This was also without it being optimal - single hose and not fully sealed room (just a window seal kit). Recently got a newer one for my mum, it's a lot quieter and still does the job great, but I can't say how it compares to mine properly as mine was also fighting my PC throwing out heat, and she doesn't have a window kit. Ever since I got it I've always said I'd never go back to not having one, & the second it dies I'll buy another without a second thought. Being comfortable sleeping at night is just too good to give up.

I brought an Argos Challenger unit around 5 years ago at the height of Summer for under £200. I'd been threatening to do it for years and snapped one day. I might have got it for less off season but the relief was almost instant. It still runs well so worth the investment. In the summer it lives in my bedroom but I only really use it when it's 28c and up. I only use it in the bedroom as it's smaller to cool and easier to use the hose. It's less expensive to run than my electric heating is over the winter. I've spent less than a £1 running it for 6-8 hours today.  The downside is it's LOUD. No escaping that
