In the past I've purchased larger
bottles of well known branded superglue and a couple of years later
when wanting to use it again it has been solid in the bottle.

I had a similar experience recently with Gorilla brush and nozzle
superglue that was only a few months old - lid broke off the bottle
revealing nothing left inside. It had been stored upright in a cool
dark place. :-(
I expected it would be better than the pound shop stuff, which you
expect to be of the use it once and chuck it variety.
