Product review (5 stars): Very good value OEM part. And a great upgrade if you don't mind getting your wire cutters out!
A very good value piece of kit. Although it's nominally a replacement for a worn out existing pulse switch, I actually used this kit to add a pulse switch to my international model 240-volt HMD200, which didn't originally come with the pulse switch at all.

Doing this did require some additional internal rewiring, and as a result it wasn't the simple 5-minute plug & play job that it is designed to be when used (as intended) as a simple repair part. However, the pulse function is great for more control over beverage mixing and helps cleaning up - much less splashing and sloshing all over the place!
