Absolutely not! Anyone who recommends you O4O PRO's is miserable and wants you to lose money. Especially when used fatshark goggles are like 120 bucks. Why spending twice or triple the price for something nearly unusable?
You are very lucky. You nearly ended up with skyzone goggles which are unusable. Only the 04X (non pro) is decent.
It's nearly impossible to fly with them if you want to do anything faster than long range flying. It doesn't make fun, since the input is very delayed. Fatshark goggles cost only 80-300 bucks nowadays, with rapidfire included. Buying skyzone would be the same as burning your money. And of course supporting a company that scams their customers.
Fatshark HDO is compatible with Hdzero and Walknsail. It's also the cheapest option, while offering the best possible experience. The lowest latency on the whole market and very good HDMI port. There is no difference between dedicated walksnail goggles and fatshark HDOs with walksnail VRx.
HDO cost 200-300 bucks with rapidfire/TBSfusion/speedzbee5.8 included.
Fatshark HDO or HDO2 (not HDO+!). And then buy the Walknsail ASCENT VRx which is very cheap. Between 80-120 bucks. The HDO is available for 200-300 bucks on the used market, with rapidfire or speedybee5.8/TBSfusion included. It's the only goggles without latency on the whole market for that cheap of a price. Only Orqa and the expensive hdzero goggles have low latency too.
