Sayhello - the reason that Oberon include two spare bungees in the pack is so that you have spares for both the one to close the cover and also the top left corner one.

The bungees are strips of wrapped elastic with a metal "bootlace tip" on each end. They appear very simple to replace. I am guessing that you snip the worn bungee, reach inside the right side of the cover and pull the two halves out from behind, take your new bungee and push a metal end through each of the holes then lay the ends flat. Once Oberon have uploaded the video of this step in a month or so we will see.

I would also speculate that if the bungees need replacing in the distant future, Oberon would be able to supply replacements as they are fairly simple items.

The button does not get in the way at all - I tried holding the cover in various ways and it was almost impossible to actually get the button to make contact with your hand. The bungee does fall where your right hand is in certain positions, but you can either tuck the bungee back behind the outside of the cover so it lies flat or just ignore it - it is very light.
