FAQ
Can I use the Venus receiver with the Tremblr?
Yes! Just attach it to the Tremblr's air hose; no extra hardware is required. Some Tremblr users report it's softer and more pleasurable/less overstimulating than the ribbed Tremblr liner, and is a must-buy upgrade for the Tremblr.
My Tremblr stopped working!
When storing the remote control, it is stupidly easy for the case to press the buttons, draining the battery rather quickly. Be careful, and keep some 12 volt MN21 or 23A-type batteries on hand. 😉 Without a working remote, the Tremblr won't be doing much.
You can also remove the battery after each session, to prolong its battery life.
