Reciprocating Linear Actuator 24V Pushing Force 6-40lbs Adjustable Stroke 0.78-3.15inch 120rpm Variable Speed with Speed Controller,Remote Control,Big End Connector and Stand Kit.

Use this for a moving display for the holidays. Love the speed control.

Do youself a favor and spend twice as much or more on a quality machine.It works. But it's more of a novelty. Seems to be powerful enough, if you can get it to stay put without rachet straps. No weight whatsoever and it just moves away with each thrust. Also it will not stay together for more than ten minutes before nuts, bolts, suction cups and even crank arms fall off. Fun times.And the noise. Remember original series star trek red alert klaxons? Yeah, great for sexy time.Bottom line, it's a novelty. For beginners maybe. Use it once or twice, decide if you really want a machine and buy a $3-400 quality, heavy machine. But I recommend starting there if you're serious. Not this noisy rattle trap.

this is not as powerfull or usefull, the bracket is useless and you cant attach anything!

Works great for size and poor. Remote is great. Easy assembky.Crappy upper and lower nuts for holding movable upright arm.Adjustability is great.Crappy hex nuts. Strip and break.Easy to get nuts at a store. But they do not have replacent parts just entire item. Which is silly

This thing is really COOL - straight forward - great control options included - ThanksOnly CON is that the T-slot grip nuts could use a bit more "gripping surface" so they don't fall out during assembly / use (but I fixed that too).
