Came in the box already opened, apparently returned. I didnt even test it and unfortunately didn't return it in time. I didn't bother testing because it just felt familiar to many other cheap off brand electronics.

Awesome

Funciono bien 1 hora, después de eso empezó a cortarse la imagen en todas las extensiones, se ambio cable hdmi, cable utp y nada lo tuve que devolver

Funciona pero no trae instructivo ni empaque, viene solamente en bolsa de plástico. Además, tiene marcas de uso.

It works very well and it got here on time. Thanks.

works perfectly ... easy to install

They work great, we have 18 TVs in 4 receivers and this allows customers to see Multiple TVS cast from multiple viewing directions.

Order received quickly and everything works well so far! :)

Good quality

Bought it for a security system. Works great. Easy to use.

I bought this to extend HDMI output from cable boxes to 2 TVs, one an outdoor TV on my deck and another in a spare bedroom. Both used 50' CAT6 cable and the picture quality and sound are great. Since both of these TVs are only 1080p with stereo sound, it's the perfect solution. I can't justify 4K TVs in guest rooms or outdoors any more than I would rent them their own cable boxes for occasional use. This is a perfect solution.

The media could not be loaded.

Bought this to simplify a splitter and two sets of HDMI over CAT6 extenders (5 boxes) with 5 separate power dongles to three boxes and one dongle.I am very familiar with HDMI extenders but this one only worked for the remote monitors at the end of the CAT6 cable. the local HDMI splitter outputs were dead. So I put a 1:2 HDMI splitter box in front of this to limp me along but I don't get the joy of simplifying my wiring closet and fewer boxes.Wondering if the local HDMI splitter portion of the circuit is even populated with components....Update: Found that the local output worked fine on another TV in my house. So I suspected marginal HDMI drive electronics such that it worked on one TV and not the other. So I inserted an stand alone 1:2 HDMI splitter between the local output. Now the problem TV works fine. So something about the local output isn't compatible with one of my TVs. The 1:2 HDMI splitter is just acting as a line repeater and seems to solve the problem. Unfortunately it adds boxes when my goal was to reduce clutter.Update 2: The vendor worked with me over a series of messages and we eventually settled in on an action plan. They sent me an EDID manager box at no charge and after copying the EDID of my TV monitor and then inserting the EDID manager between the Extender Splitter HDMI Output and my TV monitor input the problems went away. While this adds a box to my system I suppose my circa 2009 TV monitor is perhaps not following EDID conventions properly.In the end this Extender Splitter is a great solution to mirror a single set top box over multiple monitors. I have three set top boxes feeding 8 separate TV monitors in my home (I bought two of these Extender Splitters sets). I am saving $50/month by avoiding five additional set top boxes. The drawback is we can only watch three different programs at any one time but only two of us live here so that isn't a hardship.Since the set top boxes have RF remotes (Xfinity X1) I don't need to fiddle with IR back hauling over the CAT6 cable which I did before with older HDMI extenders I used. The CAT6 extended monitor only need a small Rx box that is powered over the ethernet so no power dongle needed at the remote locations.Kudos to the vendor here solving my problem.Update 3: I ordered a HDMI Cable Extender (buffer - amplifier) (https://www.amazon.com/dp/B08CC9J7P1?psc=1&ref=ppx_yo2ov_dt_b_product_details) and inserted it in place of the EDID manager. This also solved my problem of local monitor not working. My guess is this isn't an EDID compatibility issue, rather a HDMI drive issue with my TV Monitor. Adding the buffer amp seemed to fix it and to my knowledge the buffer amp has no intelligence to monitor or manipulate EDID messages. So if you buy this product and have troubles with the local HDMI output ports, a $8.69 HDMI amp/buffer might solve t for you as well.
