I love BR! I've used BR ~10times in the last six months (only renting items, including for one photoshoot) and find the platform really effective and delightful with an amazing selection of clothes. I keep coming back and love that I don't need to buy something new for events that I'll never wear again. I usually rent dresses or signature items (e.g. a jacket) and sometimes handbags. The app is easy to navigate and the process to rent/return was so simple as they take care of cleaning etc. I haven't yet tested renting out my own wardrobe but plan to soon. The BR team is always very friendly and responsive too which helps.
I've only had one instance where the rotator didn't respond at all to my request which was frustrating but ultimately not the platform's fault.
