Product Review

The Brain Premier tDCS device is probably the most affordable and easy-to-use transcranial direct current stimulation (tDCS) device on the market today. The device features a simple to use interface that allows you to set the time and intensity. The LCD screen will display the current being output during a session as well as the time remaining. Bra

One of the advantages of the Brain Premier tDCS device is its user-friendly design. The device comes with an intuitive control panel and an LCD screen that displays the current intensity, duration, and battery level. Our favorite feature about this device is actually the accessories it comes with. 

The brain premier starter kit comes with a super convenient pre-marked 10/20 electrode placement cap, unlike any other starter kit. This makes the electrodes easy to position on the scalp, ensuring a comfortable and effective stimulation experience.

One of the standout features of the Brain Premier tDCS device is its precise and accurate stimulation delivery. It is equipped with a microprocessor that controls the current intensity and duration, ensuring consistent and safe stimulation. The device also has a built-in safety feature that automatically shuts off the current if the electrodes lose contact with the skin or if the current intensity exceeds the set limit.

Another great feature of this device is the rechargeable battery. There’s nothing worse than getting all ready to start a tDCS session and realizing your 9-volt battery is dead. Not everyone has a bunch of those lying around the house. The good thing about the Brain Premier is that you can quickly charge the device using the included USB-C cable. The only con about this is that the battery is built into the device, meaning if the battery dies over time then the device would need to be replaced. However, batteries these days are well made so we are ok with the risk due to the convenience of having the rechargeable battery and the low cost associated with the device.

Overall, the Brain Premier tDCS device was tested as a reliable and effective tDCS device. Its precision and accuracy, along with its user-friendly design, make it an attractive option for individuals who want to try tDCS from the comfort of their own home. The device is budget friendly but still has all the features you need in a tDCS device.
