Variable Speed Controller | Converts 2-Speed Wands into Adjustable-Speed Models | Plug-In Control Box with Dial & Belt Clip | Adds 2.5 Ft Cord Length | For Massagers

This is literally just a router speed controller, from Harbor Freight, with Hitachi-specific silkscreening. You're paying about a $5 premium for that blue ink. But it works, and it works well, because an old Hitachi is just a motor in the same way a router is just a motor.

I bought it as a gift. My girlfriend says that it gives FAR more control than simply a switch and has increased her pleasure with her Hitachi wand 100% Well worth it.

Received today and out of the box the variable speed functionality doesn't work. As in, it doesn't even power the device plugged into it. The full power switch setting does work, but that's sort of stupid for a variable speed accessory to NOT work for the variable speed purpose Super unhappily surprised THIS IS A NON-RETURNABLE ITEM.TOTAL WASTE OF MONEY. COMPLETE PIECE OF CRAP. STUCK WITH A PAPERWEIGHT NOW. Very unhappy customer and will avoid this vendor completely.

Low low to wide open just works well!

The magic one has quite a kick. My beautiful partner said that it was a bit fast. This promised some speed reduction and did deliver but it’s tricky. I would think it would be smoother in the throttle curve. other than that, it works well.

Love this. Works great. We have two wands. This only works on our high and low speed wand. Will not work on the multi-function wand. This item is great though. Allows you to make the wand a variable speed instead of high low.

Good thanks

This unit is perfect for the Hitachi wand.Do NOT use this with any other massager or anything else, or the motor could burn out.
