Well, I noticed some cracks in my 5 week old Elite Strap last week, got in touch with Oculus Support who took until this morning to reply, and basically told me to get lost as I bought it from an unsupported retailer - OcUK.
Posted in the support forum and had a reply and RMA details within 8 minutes, so 10/10 customer service from OcUK (as always), 0/10 for Oculus!
Unfortunately, as it was bought b-grade there is no more stock, so it's going to be a refund and I need a new strap - having no confidence in the official one (or Oculus support), and looking through this thread, there seem to be a few options:
MVH
GOMRVR
BOBOVR M2
So far, the BOBVR looks the best, but delivery estimate is 3 weeks :/
There's also a "3XS" branded one which is on Prime delivery for tomorrow - anyone had any experience with it?
If possible I would like one which I can fit headphones over - it just about worked with the official strap. Failing that, I guess it's time to grab some decent earbuds!
