I have brought many products from this company over the years, mostly from third party suppliers like ARB or TJM & having them fitted by the same company

As always the quality of the product is faultless and fitment of my centre console, roof console , door trims & speaker pods was very simple

Quality product. The front mounting doesn't line up easy enough. Hole needs to be in a different position
