PERFECT I ordered the vents to replace shorter older vents which are no longer available - they let the house down as we are working through decorating the house room by room. After researching a LOT of vents and reviews, i had a couple of questions from various suppliers. When phoning Tradefit they answered promptly and went to measure at my request. These vents seemed a good mix of a clean look, good function, aesthetically pleasing and competitive price. The vents arrived the very next day which was not necessarily expected. I ended up fitting them all that weekend, in decorated and undecorated rooms - they were easy to fit and consistent in size, fitting and colour, with each other. All fittings were supplied and all vents operated smoothly. The vents are fantastic design and quality, especially for the price paid, and have improved our windows no end. I would buy from Tradefit again without hesitation. Stephen
