We have received many suggestions over the last 2 years and we are very grateful to all who took the time to make them. Ultimately, we determined that the device’s functionality and overall customer satisfaction rate was very good. The main three things people frequently commented on were:
1: They asked for an easier way to install the battery.
2: They asked for a more corrosion resistant electrode cable.
3: A very small percentage of our customers used weak saline and had issues getting a good electrical connection. The device would take a minute or so to reach 2mA.
In the process of adapting the current device for an easy to use battery compartment, we realized we had plenty of room for 2 battery compartments. That would allow us to use 2 9-volt batteries in series and step up the voltage to 18V while still maintaining the same current regulation properties desired (current max limit to 2mA). The higher voltage is akin to more torque; it gives the device more power to cut through any inconsistencies with the saline solution and allow for a more reliable and immediate connection. We created a prototype and tested its reliability extensively for over 6 months. The final result is the ApeX Type A 18V Edition. That resolved two of the mains requests. The cables were still a problem. The reason is because we were working with our engineers to come up with a way to fasten the cables to the mesh using banana plug connectors that were not welded. Most solutions on the market are welded and corrode very quickly. We had custom plates and rivets created out of the same molybdenum rich alloy classified as marine grade stainless steel or 316 steel. After creating the electrode connectors we always wanted to give people, we then asked our cable manufacturer to help us with corrosion. They came up with a 24hrs long corrosion resistance process that causes the cables to be very corrosion resistance. In fact, we have not been able to corrode these cables with the brutal in-house testing we are performing yet but we are still at it. We don’t want to claim they are corrosion proof yet. Maybe in a few months.
Absolutely. We utilize PayPal as our credit card processor and all credit card numbers and pertinent information is transmitted directly to their servers. We do not store any credit card information on our site and communication between the customer’s computer and the credit card processor is encrypted using the highest available commercial encryption system on the market today.
Recently there was a flurry of new tDCS devices released in the market that lack any real advantage or innovation over the existing products already for sale. Some unscrupulous manufacturers started to tell people that only higher voltage dual battery systems or exotic and expensive 23 volt batteries (usually used on garage door remotes) are capable of o delivering enough voltage to overcome skin resistance.
That information is simply not true. A single 9 volt battery is not only capable of overcoming skin resistance without any issues, they are also much more comfortable for the end user as well as cheaper to operate.
We at ApeX Electronics believe that the job of popularizing tDCS needs to be done responsibly. The increased risk a higher voltage system exposes users is not acceptable to us. So the ApeX Type A continues to offer the same great performance without exposing our customers to potentially dangerous and unnecessary voltage levels.
Devices sold worldwide have been delivered without major issues however international customs is completely out of our control. While we cannot guarantee it, we can work with our customer to ensure the best possible chance of the item being delivered without delays.
No, the unit cannot be modified to output higher levels of current. We highly discourage people from modifying the device in any way. Modifications to the device void the warranty.
Any and all electrodes rated 2 mA or higher are compatible with the ApeX Type A. The best ones are sponge electrodes soaked in saline. ElectroSquare makes one of the best in the market and that’s what we currently sell with our Ultimate Bundle. However, if you have other electrodes, you can certainly use them if they are rated to 2 mA stimulation. Adapters for other electrodes are available within our Store.
The battery is located inside the unit. To open the ApeX Type A you need a smal Phillips screwdriver. Once open, the battery compartiment is located on the back of the X1 unibody panel circuit board assembly. Instructions on how to replace the battery are available in the ApeX Type A User Guide.
It allows for the connection of up to 4 electrodes at the same time, for the users convenience. Current is split under these circumstances.
While the ApeX Type A is designed to limit current flow to 2 mA maximum, the buil-in meter goes up to 5 mA as a safety precaution.
The package does come with printed instructions on how to set up the device, test it and get it ready for use. Instructions are also available in the form of a PDF file regularly updated for the most accurate and up to date information. You can find that within our Knowledge Center page.
tDCS placements are easily found online, a good independent example is www.tdcsplacements.com. We have gathered information about tDCS placements and will be adding it to our site shortly.
