Ok, Studioform impressions! My 'Enthusiast Kit' arrived today which includes both the counterweight wrap (which currently has 4 taped together AA batteries in it) & deluxe strap (which rests on your head under the normal strap and fixes to the top with velcro). I have used it for a couple of hours and I am really happy with it.
The quest has quite frankly been at best uncomfortable and at worst painful since I have had it, I think the longest I have previously played in one go was about 45 mins. I have just played Thumper this evening for an hour and a half and could have easily carried on if I had more time. It took a bit of tweaking to get the fit just right (I basically needed to let out the top strap pretty far) but the padding now makes it so pressure is even (and soft) & the front heaviness is distributed properly over the head.
To be honest, I find it really hard to trust youtube reviews for Quest & VR gear due to the amount of positive reviews there seems to be for complimentary products. As someone who went and purchased this though...it has made the Quest really comfortable to use and means I will be able to use the headset for longer sessions going forward which is really exciting. Playing Thumper was probably the most immersed I have been using the Quest as I was not having to adjust the headset every few minutes.
Also...Thumper is just excellent, very much worth a go at the current steam sale price.
