The backlight works great. Really close color match. The only complaint is that the adhesive is pretty bad on the strips, but the provided hooks keep the strips in place. Take the time to properly calibrate it. Also, a tip I learned is backing off of the saturation-mine is set at 18 percent- to get the most variety of subtle colors.
Govee manages to make its TV backlight affordable by using its Envision camera versus kits like the Hue SyncBox that use a directly reading HDMI pass-through box to read the signal and output complementary color. This kit from Govee is not as accurate or as quick as Hue's setup, but the cost is about one-fifth that of Hue's system.
Are there further reasons to get the Govee system besides it being $400 cheaper? Yes. The Govee works without HDMI pass-through, meaning that if you have a TV with built-in apps that don't require use of an external Google or Fire or Apple dongle, you can still use this system for backlighting. The Hue system won't work without an HDMI feed to your television passing through it. Further, the Hue system does not work with DRMed feeds such as Netflx, etc.
This Govee is great tech at an excellent price. If you don't need the fanciest, costliest system available, you might find that you not only save money but have more fun with this Govee camera-based system.
