“The supplied ring was the right diameter but the fitted wheels were some 12mm. This meant the glass turntable was lifted to a height above the drive motor. Fortunately, I was able to take 3 10mm wheels from an old microwave and swap them. this was not without difficulty as the plastic (of the ring) is quite brittle. In addition, when ordering the ring I paid for it (via Paypal) only to discover later on that postage was required and this was added on. Hence I paid £4.95 then later £8.90 (ring + £3.95 post)”
