I have a Lithtech Smart Chair 1 which I have had for a year or so and I am very happy. Looking at their website I can see that they have released some new models but I am very happy. They are on the pricier end £1750- £2500 but have been reliable If you look up the company on Youtube there is an abundance of videos.
