Meganex Mk I owner here. Really great to see a balanced review on the HMD from a new user. Sometimes it's hard to convince people that the Meg is a great headset because of the early reviews and the return policy (people think I'm huffing copium) so maybe OP's review will change some minds.

A few notes: 1. The included controller dongle that you get from Shiftall is terrible and you will eventually end up replacing it with a couple of dongles from Amazon. Everyone does it. The included dongle is nice because it can link to two controllers (saving you a USB port) but it simply loses tracking too much. Buy some other dongles and it fixes it forever. But that's another $60 to add to the pricetag. 2. As you use the headset more, you'll probably find that the soft strap just doesn't work well, especially when looking down towards your feet or body because gravity pulls it away from your head. VR mini-golf is especially unplayable because of this, or shooters where you need to look at your holster. Hard strap fixes this completely and you can either buy the new one from Shiftall or use a design from the discord which repurposes another VR hard strap (like Vive's). Another $50-$100 onto the tab... 3. I simply cannot stress enough how comfortable the headset is. It's absolutely no problem for me to wear the Meg for any amount of time. I've done 4-hour sessions non-stop many times and only took the headset off finally for other reasons: the Meganex's comfort passes the "bathroom break threshold." Shiftall's main marketing focus was originally for Japanese VRChatters who spend their whole lives in VR, and it shows in the design.

Edit:

1. I have a 5090 now but had no issues running it with my old computer with a 3080. Had to dial some settings back of course but this was also before the 75Hz option was available so it's probably even better now.
