I assembled it but ignored most of the segment joining holes and drilled fresh ones, making sure the front faces lined up which they don't if you use their holes!
I have mounted it on the front of my i.2 metre prime focus dish and after initial alignment it gives about the same RX performance as the 1,2 metre dish - maybe 1dB more - but on TX i now find that it only needs half the transmit power of the 1.2m dish.
This is 3db better which is about right.
I have still to fine tune the pointing but the results are not bad. I can equal the beacon at 2M/S with only 80 watts transmit power and to equal the beacon at 250K/S I only need 14 watts
There is now less risk of overheating my PA.
Receive MER of the beacon is only 9dB so the accuracy of the dish pressing for 10ghz is very poor and around 2dB down on what id should be.
My beacon MER was only 10 dB yesterday with my 2.4m dish. However I am seeing the transponder noise floor at 5 dB above the receiver noise floor. It might not be as bad as you think. The beacon MER is not a good indicator for larger dishes.
It arrived somewhat worse for wear - dented from poor packaging - so got a partial refund for that.
Assembling was a nightmare - holes for the segments did not match up and also required much drilling and filing to get segments to line up. I used the supplied mounting stand and there were a number of bolts missing so a trip down the road to the local builders merchants was required.
The LNB mounting arms were twisted and required bending to get them to fit - I will probably replace those soon.
As for receive I found my 1Mtr dish gives a better signal, so for time being I am using that.
It's probably not aligned quite correctly yet, but I have found that 6W works well, at 125 K/S, 12W at 250 K/S, and around 24W for 500 K/S, so seem to be getting the same performance at 2.4GHz transmit. Based on that 80W seems about right for 2 M/S.
Until I get a bigger amplifier can't do much more.
