Being one of the lucky few to get my Steam Frame a few weeks ago, I have been using it quite a bit since then. I have been buying some third-party accessories to mitigate some of its weaknesses.
First the obvious one: it is surprisingly light and small, but overall not comfortable enough due to my glasses. To solve that I went ahead and bought prescription lenses from VR Optician (119€ including fast shipping and additional prescription fee).
Then I figured I had better protect it against sunlight because I do not have one of those fancy head mounts nor do I want to pack it in its box between each use. Thus I got an AMVR lens cover that fits quite well (13€).
And finally the battery life situation is... Well it's bad. I got decent VR legs and can play for hours, but the battery only lasts at most 1h30 when running PCVR at 120Hz. So I got myself a UGREEN Nexode 145W 25000mAh Power Bank (56€), 2 short angled USB-C cables (24€), round magnetic USB-C adapters (16€) and a small fanny pack (10€).
I will also say there has been some trial and error regarding the magnetic adapter. The idea is to protect the headset port in case the cable snags on anything. I wanted to plug it directly in the headset port, but it tends to disconnect when I turn my head. The tradeoff I landed on is : one very short cable plugged in, magnetically coupled with a longer one that goes to the battery. The 240W-rated USB-C cables are also overkill but hey, not that much of a price difference (they are quite thick though and contributed some in my disconnect issue).
So there you have it, 238€ on top of the initial Steam Frame + ergonomic accessories kit purchase (which is a must-have if you ask me), not counting said trial and error.
Update: there are strong arguments in comments against using magnetic adapters. I'll be ditching that and keeping the 2 cables approach so that there is a straight connection (hopefully weaker than the angled plugs) that can unplug more easily than the battery or headset side if the cable snags on something.
I’ve been loving my frame, but I didn’t realize how much I needed those prescription lenses in there. I just ordered them for about $60. I was going to get a smaller pair of glasses that would fit in the headset, then I remembered seeing the lenses on the store page.
The ergo kit was out of stock unfortunately, but I can’t say it’s “mandatory” like some others do. I might buy it when it’s back in stock, but I’m not in a rush as it feels alright as-is.
The fanny pack is interesting, but I think I’d rather just get a long cable and tether to a wall. Maybe I’ll feel differently after some extended use.
Depending on what you're playing, it can be an option. If you're playing a high movement VR game - something like H3VR - that'll send you to yoink city eventually. I had to specifically lay out my Rift and Index cables with games in mind.
If you're on the couch or maybe playing Beat Saber, a game that doesn't have lots of 360° movement it might be doable.
