AIBU or are these little pots just not fit for purpose?! I’ve bought 6 and am currently using them on holiday - well I saying using them - we’ve had to pop the roller out of them all as the roller ball either doesn’t move when trying to roll it on skin or dispenses the smallest bit of cream before becoming stuck again. What’s the secret to getting these to work - am I missing something or are the balks just too big for the pot?! I don’t have this problem with my roll on deodorant 🙃
