I bought this for my 2007 LR3. This is quite a high mileage so I didn't want to spend a lot of money OEM/Arnott. The installation was quite easy, the air spring looks high quality. I've ridden about 20 miles so far. I will update this review if anything changes. For the price the quality is good. I've seen cheaper on eBay even though they had no reviews. The best installation video I found was made by Atlantic British for a Range Rover Sports (same chassis and gearbox as the LR3). The hardest part is the air rebar, which the Atlantic British video shows quite well. I was looking for this company maxpeedingrods that makes many different auto parts, connecting rods and turbo suspension components. I bought an Arnott air spring for my full size range rover, upon inspection the quality was slightly better, although not more than double the price.
