I took a punt on this as I had heard good things about the Mars 300 system and the 400S too, and figured that this would be nice, simple, intuitive, robust, and just basically work well. It has pretty much matched my expectations. Great product.The one area where perhaps the units that cost several times more are technically better, is perhaps the latency. I have tested the latency and find it completely usable for everything including most follow focus work, with my Blackmagic Pocket 4K, but most of the latency is from the camera anyway, not this product!I want camera equipment that work right out of the box, every time, reliably and simply and intuitively. I had this thing working in minutes without even glancing at the user manual.PROS:Low latency (under 100ms, but add to that the camera you're using's own inherent latency over HDMI)Best price for any device that does what this does (reliably beams 1080p60 over 100 metres perfectly)Simple, intuitive controlsReplaceable antennas for durabilitySolid metal casing with nice robust feelTakes Sony NP-F batteries, and lasts 4 hours on a 750 sized one.Very long range transferCONS:No SDI ins or outs, unlike more expensive versions, such as Hollyland 400SNo screen unlike more expensive units, such as Hollyland 400SCase is a little bit small, requiring dismantling of batteries and antennas to pack awayThe PROS heavily outweigh the CONS on this one.A highly recommended, excellent product.

For the money, these unit are well put together. They are reasonably sized when mounted onto medium and large cameras, but when mounted on a DSLR they are quite large and can affect balance and handling. Having NP battery power is a great choice as the batteries are easy to find and well priced. The units also work with DC power at a wide range of voltages. Having an HDMI loopthrough output is essential to have an onboard monitor as well as wireless remote monitoring. Latency is a bit higher than I am used to with my Aries Pro wireless setup and the units do make a bit of noise while in operation, so I don’t know if this system will replace my Aries setup in the future.. We’ll see.

Bought two of these to use for live streaming - the quality is superb and the units are totally plug and play - just switch the TX and RX on and they connect to each other automatically.Have used these from one end of a Church to the other and had no issues ever with signal dropoutWould totally recommend these units for professional use

I bought this for live streaming in a church to extend the range of our cameras. The product arrived well as expected and works fine. But I was disappointed that it wasn’t provided with the necessary batteries, and with only one power cable. Therefore it wouldn’t work until I bought the battery packs separately (which were then not available) or bought a second power cable (for £30). Spending £400 on a product I can’t use out of the box isn’t acceptable, so this should be made clearer on the page. Also the lag appears greater than the suggested 0.1s - not a huge issue but needs consideration if you have a separate audio input.

Great product especially for outdoor events or anywhere you need remote cameras. Simple to setup and use the indicators tell you status. Picture quality excellent.
