JQDML Upgrade Reciprocating Linear Actuator High Torque 40 lbs, 24V, 120rpm | 1.18"-6" Adjustable Stroke, with On/Off Speed Controller, Perfect for Small Automation & DIY Holiday Motion Decor

No issues it is working as expected. There were some instructions in the box but really folks? All you need to do is attach the two wire fast-on connectors on the Female power connector pigtail to the two motor terminals. I am not sure way they sent two pigtails, one without the fast-on connectors and one with the connectors. Easier to uses the one with fast-on connector that slid on to the motor power tabs. Be gentle people. The motor tabs are not super strong and could be bent off if to much force is applied. The only adjustment is the position of the shaft to the motor arm and attach the motor arm to the motor shaft. Motor shaft arm position example is if you want a two inch shaft travel just attach the shaft one inch from the motor shaft. Any other travel you want will always be 2X the distance from the motor shaft to the shaft knuckle. Mine came with the shaft travel set for the max travel which I believe is 6 inches. I only needed 3 inches of shaft in/out travel so I set the shaft knuckle 1.5 inches from the motor shaft.

attempted to use this as a holiday decoration movement device, for hand waving and such on VERY light items, the reality is this thing try ed to start a fire, its poor quality and bad parts for anyone wondering how the item works or..doesnt in this case if you have it pointed straight up with ZERO load it cant even lift the weight of the main rod at anything less than half power and will stall out under its own weight, on level use it stalls out under the slightest loads, but worse youll think its working untill it just stalls at random gets hot and burns out

Product works great. Not enough power for what I needed it for. Could have a better connection for the battery to the device.

It doesn't come with a stand unless you want to pay another 100 so I made one which was relatively easy I used a cast iron table removed the top and bolted the liner actuator to it, I've got the suction cup adapter on it which works well if your toy has a strong suction but not so well if it doesn't. I'm giving this 5 stars for the price and capabilities of this model compared to ones that are specifically geared for sexual functions this is cheaper, faster, and has a much longer stroke length than other items I looked at.

Worked great at first but within the first two months the motor burned out leaving it to be a large paperweight. There are no replacement motors available for sale so don't really know what to do with it, there isn't even a easy way to contact the seller to request to purchase a replacement.

bought this to use as last one did nothing, this was to have some torque to it and still nothing very much the same as the first one. Wont be buying this again

I wouldn't say powerful motor. But it does work until it doesent
