Have had one in this house , which is 15 years old .
It is pretty air tight , the piv unit failed did we notice- no.
After repair I couldn't see any difference.
Talking to tame building surveyor he did say that the trickle vents in the windows were probably just as good .(Scottish building regs).
I have looked at heat recovery which will probably be part of my strategy when I go heat pump.

I’ve installed a couple of them, in my Mums house (20’s single skin bungalow) she thinks it makes a big difference, in mine (50’s cavity wall which I stupidly had filled - hence the PIV) it’s negligible and better trickle ventilation made a bigger difference,
as above.
as above.
I put MVHR in when we built our extension. Previously with 5 of us in the house the windows were covered in condensation and the bathroom grew mould for fun. Now, all lovely and dry. Didn't have to have trickle vents in the new windows - let's face it buying triple glazed sliding doors and then having to cut vent holes in the top is a bit daft!
Well worth the upgrade to MVHR if you have access to put ducts in.

makes me laugh everything i double glazed and insulated to the teeth draught proofed and you then put vents in the windows and doors to let draught in 
Yep, and that's the building regs making you do it, so MVHR is a no brainer to me.
I was quoted a crazy sum by a recommended company, so I got the gear from https://www.bpcventilation.com and installed it myself, think it was under 2K for 5 bed 2 bath large detached house.
