I have been most impressed with the excellent service provided by Stove Fitter's Warehouse. All the parts I have ordered have arrived in good condition and in good time.
The Base Support Unit is very well made and very strong. All the edges are well finished and the holes are cut with great precision. A minor improvement would be to have a different array of slots in the flue section compared to the triangular supports - this would allow even greater flexibility in positioning the flue.
All in all, a really first class product backed up by superb customer service.
