To date I haven't any problems with my P4PV2.
I've flown it both at Sea Level in CA and with takeoffs up in the Rocky Mountains at up to 10,000' plus MSL.
I've never lost a signal even while shooting a video at 8,000' ASL down as low as 15' AGL following and circling a friend bale hay who was a half mile away "below LOS". This was in an area miles from any WiFi and other types of interference.
Last week I was in Silicon Valley that is loaded with all sorts of 2.4 Mhz, 5.8 Mhz, and other electronic interferences demonstrating to my son at Sea Level the P4PV2 precision RTH capabilities when it came back and landed without assistance to within 2 inches on a small paving stone from where it took off from.
I also have a MP that lands where it took off from and a I1V2 that I have to assist with the RTH landings. My P3P, like my I1V2, would return.
I remember a couple of years ago of how my new at the time P4 amazed me and friends when it would land within 4+' from where it took off from.
