Recently I have had an opportunity to test this video transmitter over the recent weeks to see how it performs
Specs:
- Switchable power output (25/200/600mw)
- 40 Channels
- 7-28V input power range
- Built in microphone
- Weight: 13g

At close look

Video transmitter comes in a small case with whip antenna and cable needed to connect it to a quad. There is two buttons instead of dip switches and 3 sets of LEDs indicating:
- Band
- Power
- Channel

Top button is for changing the output power. Bottom button is for changing bands (long press) and channels (short press).

Testing

I have installed VT241T on Lumenier QAV-ULX quad to test the transmitter in the air.
The most important thing for me was how does it perform on 25mw (crucial at racing events). I have found that generally on 25mw it was pretty clear. There was some noise in-between the trees but with others flying with me there wasn’t much bad interference . 
At 200mw and 600mw video was also quite clear. I haven’t personally seen much difference between the two power settings in the forest location I was testing it. 600mw makes the most sense if an aircraft is much further away. 
DVR Video at 25mw  
DVR Video at 200mw  
DVR Video at 600mw  

Conclusion
Overall not a bad video transmitter. It offers switchable power for a relatively low price. Changing power, band and channels is very convenient with two buttons and LED indicators meaning no more dip switches. Supplied whip antenna performed very well. Didn’t notice much difference in performance between that and ImmersionRC Spironet.

Nice review and thank you! Im a fan of the switchable style vtx's.

Is this a rebranded eachine et526? It looks similar on pictures

It looks similar indeed but from what I was told by FrSky  this one has a silicone wires and Cleanswitch function that doesn't spill on powering up. Can't verify that because don't have ET526 to compare with

Cleanswitch? Could you explain a bit more? I know that the eachine doesn't power the output signal untill you double click the power output button, and when the output is not powered, you can change channels without the risk of disturbing anyone.

But from my own experience, the eachine on 200 and 600mW tends to spam my friends video feed when I'm too close. My vtx is on 5645Mhz, while he is on raceband 8 (5917Mhz?) And running a TBS or immersion vtx on 800mW

That's according to the product description at HorusRC"CleanSwitch will ensure that your video transmitter is interference-free while powering on, or while changing channels. All current video transmitters swipe across the entire band while being powered on, often resulting in flickering and heavy interference to anyone in the air, regardless of video channel chosen. VT241T CleanSwitch will allow you to power on and change channels while your buddies are in the air, without any external interference. CleanSwitch is race friendly, and pilot friendly ... "

I was flying with others using this VTX and we havent noticed any spilling but this is more of a feature that isn't easy to prove working other than my word
