Hi yes I did install it myself and I will be honest I am definitely going to be doing a review video but answering your question I wish I had purchased it sooner for my upper application and what I use it for it's absolutely perfect and also I'm very happy with the machining work of said unit as well and also have never opened a Land Rover transfer case before in my life I found it very easy and simple to install obviously using @syncrogearboxes installation video as a guide, there is a direct link to the exact unit I purchased from the company in the description of the video
