You may receive a security warning when installing- please be assured that this software has been extensively tested so you may select to proceed. Click More Info to reveal the Run Anyway option:



    Download the ElectraStim update software which is packaged as a zip file (please note that this software is only suitable for Windows 10 PCs and not Mac iOS)

    We recommend creating a new folder in your Documents on on your Desktop. You should then place the downloaded zip in this folder and double click to unzip. This will expand into 3 folders and an exe file. Double click the .exe file to install. 

    The screen below will open. There are only 5 steps to update and this should take under 2 minutes from start to finish.


    Step 1: Plug in your stimulator and ‘COM’ will appear in the box, as below. We find that plugging your stimulator in after the application is open works best, but if COM5 does not appear then please remove and reinsert the cable until it appears.

    A number will appear after 'COM' but this is not relevant and will be automatically allocated by your PC. As long as COM appears, everything is working correctly!


    Step 2: Select your stimulator model.


    Step 3: You have the chance to review the firmware update notes by clicking the pink link. Please note that once you have installed the update, this is not reversible. Once you're happy to proceed, click I Approve.


    Step 4: Click the Update button once to upgrade your stimulator. A progress bar will display. Do not remove the cable or press any buttons on your stimulator until step 5 is highlighted.


    Step 5: That's it! Disconnect your USB cable and try out the new features of your stimulator.

    If you experience any issues with this software, please contact us directly with your stimulator serial number info@electrastim.com

    ElectraStim test drive

    It really is too soon to give a detailed review of this box of electric wonders. With so many permutations possible with the drive electronics, the mixture of the acoustic tracks, the accessories and places to use them, the mind is boggled by the possible combinations. I have only just scratched the surface of what can be done and the sensations that can be produced and there are some settings I have not even tried yet. It is a pleasurable work-in-hand, suffice it to say it will amuse and stimulate for years.

    Easy, simple, user friendly.

    Easy to use.
