Detailed XFT-502 Review

Introduction to the XFT-502

You will learn all of the basics in this XFT-502 review. This device is another tens unit product from Shenzhen XFT Electronics which we talked about in our review of XFT-320A. It looks like this tens unit is not quite as popular as the XFT-320A from what I have seen in Amazon reviews.

At the time of this review, the XFT-502 was available from three different sellers on Amazon.

Throughout this review we also aim to compare tens units.

XFT-502 - Features

Four Modes

4 TENS Modes

Like XFT-320A both units are based on Traditional Chinese Medicine. There are four main modes which the device contains and they are:

  • Tapping
  • Vibrating
  • Massage
  • auto
  • Each mode has its own button on the device itself. Many other units have more modes and programs to choose from for more options.

    There are only three main modes of speed. As there is a button for each mode there is also a button which controls the pulsing speed of the electrical current.

    Vibrations in the massage mode are said to make the massage experience more pleasant and effective. The waves are low frequency.


    Most Tens units are dual channel, and that is also the case for the XFT-502. It can be connected to four pads (two for each channel) and you can adjust the channels separately so as to focus on either a large part of your body or two areas at once. Having two channels can come in very handy.

    XFT-320 is also a dual channel unit.

    Intensity Levels

    Aside from the modes and the speed there is a button devoted to the intensity level of the device, and it is called the Strength button. It allows you to switch from one level of intensity to the next. As with the XFT-320A I am unable to find the precise number of intensity levels the unit provides.

    Using the XFT-502

    There are kind of a lot of buttons on this device, so I imagine that might be a little confusion for some people. It may take you a little time in order to get acclimated to how the device works.

    If you are looking for a Gold Hand XFT-502 user guide, I found this google document here while searching Google. In my opinion one of the greatest things about the Internet is the fact that you can find the instructions to almost anything. User manuals are a very important element in owning and operating any Tens device.

    If you purchase the device from China then you may end up with a Chinese manual, as some buyers have complained. The above document may help you out when it comes to tens unit directions.

    Mobility and Size

    Gold Hand XFT-502 - Size Comparison

    It is approximately 2.36 (W) x 3.93(L) x 0.59(H) inches (60 x 100(L)×15 mm). These dimensions are according to the manufacturer page. The page also states that the unit is 2.12oz(60g), so evidently it is lighter than XFT-320A which was stated to be 3.5oz (100g).

    Overall it looks to be quite small which is perfect for easy mobility. Evidently it will fit snugly in your pocket for easy portability.

    AAA Batteries

    Gold Hand XFT-502 - Batteries

    oThis otc tens unit uses AAA batteries. According to the manufacturer website the batteries will last as long as they do in FXT-320A—which is 2-3 months if you use it for 30 minutes a day. FXT-320A had some reviews mentioning that the device did not have a very favorable battery life, but I do not know about the FXT-502 by comparison.

    It may have the same issue, or it may not. Part of it may also depend on what mode, speed, and strength you use most.

    What Else You Will Receive

    Gold Hand XFT-502 - Accesories

    The unit comes with two pairs of massage pads (four total), two electrode wires, pad housing, one pair of batteries, and one manual. Obviously at some point you will have to replace batteries as well as pads.

    Replacement pads can be found on Amazon. If you need a little guidance, I suggest going here for two pairs or here for four pairs. These electrodes for tens units can be used for both XFT-320 and XFT-502.


    I wasn't able to locate the warranty for either the XFT-320 or the XFT-502. In order to figure out the refund or guarantee available on this device you will have to directly contact the manufacturer and (if it applies) the third party seller you are going through.

    in my review of the XFT-320 I suggested keeping the receipt if you choose to buy this Tens unit and overall I think it is good advice. Just in case something breaks it's important to have some proof of purchase.

    Gold Hand XFT-502 Price

    You can purchase this tens unit on Amazon for varying prices. It is sold on ebay for anywhere from $24-$140 and it can also be bought on Price starts from $13 and up to $84 with free shipping options.

    Ordering XFT-502 from AliExpress

    If you have not ordered from AliExpress before it don't forget that it will be shipped from China, and it could take up to 40 or more days to arrive in the United States.

    Overall the unit can be found for relatively cheap if you look in the right places.

    Customer Reviews

    There are not a whole lot of XFT tens machine reviews about this device—especially not compared to the XFT-320. It can be found here where one customer was not happy with the electrical cable. It does not have a very appealing rating from this seller.

    There were some positive reviews but there was also criticism about the unit being too weak, which was the same issue with the XFT-320A, according to some people. Some people claim that the device is too small so that they can only use it on one part of the body at once.

    Final Thoughts

    XFT-502 Muscle Stimulator

    The Bottom Line

    These are some points to consider if you are going to buy a tens unit like XFT-502. Although you can get this product as low as $13 from, our preference would be to go with a product like Tens 3000 or Tens 7000.

    I have reviewed Tens 3000 and Tens 7000 which can be found here and here. Both tens units are small in size and provide full control of your tens experiences, pulse width, frequency, aptitude, and so forth. The Tens 7000 is one of the highest rated tens unit with thousands of online customer reviews and 5 stars ratings.
