At first I was quite skeptical, since the original spare parts at least 3-4 times as expensive. Although I still can not make any statement about the durability after installation, one thing is clear: the dampers are 100% identical. Even the Suspa type label is be printed with the same logo as the original, only missing the course Miele identification with their SKU. Have the damper installed in our Miele Mondia W809 - the exchange was done in less than an hour.
