Question about Thumper Mini Pro 2 Massager
All visable screws are out but the two piece casing still feels screwed together at the motor . the handle at the cord inlet pulls apart enough to see the switch but no futher.i don't want to pry and break casing, hope you can help. thanks chris
I just decided to try to fix mine. There are all together 5 screws. The two on the handle are covered with plastic caps which can be pulled out by sticking a duct tape and pulling it up. The other three screws are in the thumper head and are covered with the purple violet rubber piece. I removed it with my fingers. There are also two plastic bolts in the head of the thumper opposite to the handle. I removed them by using a sharp knife to loosen them and pulled with pliers.
I purchased two thumpers over time and in both the switch failed. I see that the switch in the handle is linked with the underlying mechanical switch by a very thin plastic piece. What a miserable design. That piece broke off in both thumpers rendering them unusable.
Good luck. Artur

I had a problem with switch and called Thumper. The girl on Phone told me to pry off the switch cover with a butter knife. I did so it was hard and went flying across the room but got it off still not working so she said clean the contact with cuetip and alcohol. Worked like a charm - you can operate the unit with the switch cover off. She is sending me a new cover and said when it comes to call and she will help put back on. Mine unit was stuck in high speed and had to unplug to shut off. Working good now just waiting on cover.

Just a note for others: had to fix thumper, and, indeed it turned out to be broken switch cover, that did not engage the 'real' switch.
However, no matter how hard I tried, could not pry off the switch cover. Had to take whole assembly apart, and then was finally able to remove switch cover.
I then cut away the trim around the switch cover plate, and was then able to put the remaining plastic "button" over the switch, which makes sliding the switch much easier, and prevents potential shock.

Thumper mini-pro repair: making lots of chattering noise
After eight years of constant nightly use, my thumper mini pro started making a lot of chattering noise. Before spending $200 for a new one, I decided to see if it was something simple, the result of stupid design as before. I had repaired the incredibly badly designed slider switch a few years before, and that had only cost the price of a small screw. I had not removed the entire case that time, it’s not obvious or easy. There are five screws and two plastic push pins that have to be removed. The three screws under the purple rubber pad are easy. The two screws in the handle are hidden, covered with plastic plugs that have to be first removed destructively with a drill bit or wood screw to expose the screw heads. The two push pins in the head have to be pried out with a thin blade.
When the case is open, you can see the motor and a cam shaft assembly leading to one side of the rocker arm. The chattering noise is caused by slippage in the wheel that joins the aluminum cam to the plastic driver shaft. There are two axes of motion in this joint, it moves both up and down and in and out. The wheel tends to slip a few millimeters out of its wheel socket when the cam is at bottom dead center, go back in at top dead center. Originally, the wheel was held into the cam with a few slot channels in the rim but they apparently wore down with use. Another example of a tiny design flaw ruining a $200 machine. I first tried putting rubber bands around the whole assembly but this didn’t hold the wheel into its socket. Here is what did work. Set the mini pro down and turn the cam so that you can work the wheel entirely out of its socket in the cast aluminum cam. It’s actually not hard to do. Clean it up a bit, as necessary, and then wind a couple thickness of aluminum foil around the little wheel and wedge-push it back into its socket in the cast aluminum cam. You might have to do this a couple of times before you get it just right. Remove any excess foil and try running the motor. Chattering vibration gone, just as quiet as new. A brutal and ugly fix, but effective, and almost no cost. Note, this area gets very hot, so don’t use tape or plastic instead of foil.

Pry off the handle switch and you'll be able to work the real switch inside with your thumb.
