Price: 9/10

At $499.99, the V3 sits on the higher end of the price range for consumer tDCS devices on the market. However, with the device boasting an impressive 5 different stimulation waveforms, its price is justifiable. The efficacy of the other 4 waveforms is questionable though, with most research being done with direct current and only some with alternating current– and fewer still with pulsed current, rippled current or random noise.

Reliability: 7.5/10

After a year of use, the V3 is still going strong! Current and waveform outputs are as featured and operation is markedly better on the V3 than its predecessor, the V2, where instances of dead batteries and dead screens were abundant. Reliability here is more of a mark on the company. does not have a history of being the most reliable company and this device has not been available for nearly 6 months.

Build quality: 8/10

The device seems solid and of good quality. The device is lightweight and very conveniently sized. The rippled quality of the casing design makes the device feel unique and alludes to one of the main features and selling points of the device—the new rippled current waveform (again, the usefulness of this waveform is questionable due to the lack of literature).

Ease of use:  7.5/10

The user interface is sleek and minimalist, with only one control point (the blue joystick); however, the product does not seem to arrive with an instruction manual—this may be inconvenient for new users that have not tried the previous V2 device. The device can also be paired with an app, however full functionality is available with just the device itself; in fact, we found the device easier to operate directly from the device itself rather than pairing it with the app due to how straightforward the on-screen menu is.

Other noteworthy features:

  • The V3 has a built-in safety feature/timer that limits each session to a recommended length of 40 minutes, the device will even warn you if you start a new stimulation session too soon after your last one. You can, however, choose to override this function if you wish in order to start another session or if you are using the device for research and are running multiple subjects per day.

  • The V3 includes an impressive collection of 5 different waveforms: tDCS (transcranial direct current stimulation), tRNS (transcranial random noise stimulation), tPCS (transcranial pulsed current stimulation), tACS (transcranial alternating current stimulation), and the new tRCS (transcranial rippled current stimulation). Again, it’s important to note that the usefulness of these additional waveforms is debatable, but simply having this extra waveform to work with is a plus compared to other brain stimulation devices on the market.

  • The device also features a sham setting, which can be used in a research setting to provide information on placebo effects.

  • The V3 is CE certified to Medical Standard 60601:2

Final Verdict: The most feature-packed tDCS device on the market– with multiple waveforms and stimulation programs to choose from. Highly recommended for those looking for a multi-functional stimulator, that is if you can find it. The device has reportedly been sold out for nearly 6 months! Score: 8/10

A great device for first time users who don’t want to spend a fortune on tDCS! Controls are very simple and stimulation parameters are straightforward and easy to set. While this device does lack a certain level of flexibility due to there only being 4 fixed current settings–most users would find these options more than enough to suit their tDCS needs.

Price: 7/10

The original price of the Brain Driver v2.1 is $199 (although it seems to always be on sale for around $140 to $150)—this device has even been found to be sold at some shops for as low as $130! Either way, this device is definitely on the very low end of the market tDCS price range.

Reliability: 7/10

The device is decently reliable and rarely faulty; however, there have been on rare occasions reports of uncomfortable current spikes in response to sudden changes in resistance. We also noticed upon testing that the ramp-up and ramp-down feature didn’t seem to work when stimulation is paused in the middle of a session, which may result in a “zapping” sensation.

Build quality: 7/10

The build quality of the Brain Driver v2.1 is relatively good compared to the bulk of tDCS devices that can be found on the market, although the plastic may feel a bit cheap. We also found that the battery is also occasionally hard to remove (at least on the device we tried), however, we doubt this would compromise the overall structural integrity of the casing in any meaningful way.

Ease of use: 9 /10

In general, this device is very easy to use, with just 5 intuitive push-buttons that control session duration and current output. A few users have reportedly struggled to follow the electrode montage/placement instructions found online on their website; however, there are many tDCS montage guides online—as well as aftermarket tDCS straps and accessories online that easily transfer over to using the Braindriver.

Other noteworthy features:

  • The device comes with 2 options of session durations of 20 minutes and 30 minutes.

  • There are 4 output currents options: 0.5 mA, 1 mA, 1.5 mA and 2mA.

  • The device features ramp-up and ramp-down for maximum user comfort.

  • The device has a very useful automatic shut-off feature when electrodes are not in proper contact with the scalp.

Final Verdict: TheBrainDriver v2.1 is easy to use and has a reasonable build quality. Would recommend it for beginners due to its lower learning curve, or for those on a budget. Score: 7.5/10
