Hi Alex. All products found in https://hdbaset.org/advanced-search/?category=Extender have been tested and work well. HDBaseT Alliance cannot give preferential treatment to different manufacturers so they cannot give advice on one product over another. If you use the link I gave you, you can find many >certified< (meaning tested) products from different manufacturers – access the link, and then use the top bar filter to find the functionality that you need from the extender set. Find a few options, then go to the manufacturer website/distributor website and determine which product that meets your expected installation criteria – price, warranty period, after sales support etc… hope it is of help.
