Decent quality/build. Wonky button backlights.
This is a competent red light/near infrared light therapy device. The critical component is the pad that has the therapy LED bulbs embedded, and the controls.  It's cogently designed, with clean, minimal aspects. This uncluttered manner also allows it to be easily set up and applied.  It comes with various belts and a battery pouch with velcro elements.  The top side of the therapy pad has a soft material that secures the velcro counterparts on the belts and pouch.  So, it's just a matter of affixing the belt, using the velcro connections on the ends to hold the pad in place.<br />It comes with two cords, very short and a longer one.  The short cable is intended to be used with a USB power bank (not included). As mentioned, there's a fabric pouch to hold the battery, with velcro to affix to the pad.  Personally, use of a a usb battery pack is my preferred mode, allowing mobility.<br />Operation is fairly simple. Plug in the power cable. A long press of the power button powers it on/off. Pressing the M, Mode, button cycles through the four options.  Each mode has a corresponding button backlight color.  Red = Red Light, Blue = Near InfraRed Light, White = Red Light + Near InfraRed Light, Green = Red Light + Near InfraRed Light, pulsing.  The button backlights did not illuminate the buttons properly, with only a noticeable coloring in one side of the M button (see attached photos).  While this did not adversely affect operation or performance, it is annoying.  And, it's an indication of lack of quality control.<br />Attached are photos to show real world images, with a series of images noting the button backlight colors per different modes.<br />Based on initial impressions, this device garners a 4 - 4.25 star rating.
