It arrived very early.perfect condition and seems to be very good quality. Very good value for money, not the prettiest looking device but definitely works well. Ventilation is an issue for me as I got it for my Renault master MK2 campervan conversion. I will be installing a better vent just for this because it makes a massive difference. The temperature in my van at the time of testing was 27.7c but in 45mins was 18c. The exhaust is very big on this but sort a proper vent and it's all good 👍
