In general they will work perfectly once you have them installed in place and up and running. The problem is that when you move the cable or device the picture tends to go black and takes a few seconds to come back again (as if you just plugged it in) and sometimes comes back with horizontal distortion lines (this usually becomes corrected ).playing around with it again) If you use this to connect a computer monitor to your computer, expect the image to disappear when you adjust or click on the monitor. Basically, if you just need a cheap HDMI cable to connect two fully stationary devices, this should be fine (my PS4 has been connecting to my TV with no problems for the past 6 months). However, if you need an HDMI cable for business purposes, this is probably not the best choice and will lead to disappointment. If you want to connect your TV/monitor to a non-stationary device (e.g. a digital camera if you plan on holding or touching it during your slideshow) expect it to be a nuisance. At the same time, the picture looks great when plugged in and not moving! Plus, if you have the patience and only need it for casual use with stationary devices, you should be fine. I will not buy it again.
