Pros: These were simple and reliable during the course of the temporary exhibit we used them for. USB power on the transmitter side made cabling cleaner, and having the receiver attached right to the remote display meant less loose stuff to secure to the ceiling. I noticed no video quality problems.

Cons: I became suspicious that these things presented their own EDID information instead of passing it through from the remote device. I can't say for sure that this is the case because I didn't put enough time into investigating, since it wasn't important for my application.

Overall Review: As you can see from the pictures (and is to be expected with this style of extender), the transmitter sticks out quite a bit. Attached to a DVI-I to VGA adapter, the assembly seemed a little wobbly, but that's not this product's fault. The grooves on the receiver-side piece with the knob and power connector were just the right size to accept cable lacing tape. I can't evaluate long-term reliability, as these were for a temporary installation. I haven't tried running these at the full claimed resolution because it's more than my projectors support it, and I haven't seriously tested the sound quality because we ended up putting the speakers somewhere else. I'd choose these again in any installation where the video source has USB for power and I don't need a local monitor at the sending end or RS232 and VGA over the same cable.

Pros: The extenders are small and reliable. We have about eight pairs installed around our building, and the only time I've had trouble with them is when someone pulled the power cord out partway.

Cons: There aren't any mounting lugs, which lost them an egg. We use double-sided tape when they're on a shelf and zip ties or cable lacing, as appropriate, for for inverted or free-hanging installation, but I'd rather have a chassis that I can bolt down.
