Yet again Bijan releases another top quality product at a great price even when consider need the 4 seasons pack for this to work. I have flown all around the East Midlands, Manchester and Yorkshire Mores, all places spent a ton of time and while the placement isn't 100% Bijan never claims that it will be and also is committed to his work so if you see any issues Bijan will fix it if he can.
Would definitely recommend this 4 seasons improvement Fall ( Or Autumn as we call it) for the UK even at double the price and I hope to see a Spring version.
