Review on ⏳ OrgaNice Hourglass Sand Timer Set - Boost Productivity, Achieve Goals, and Manage Time Effectively with 30 Minute & 5 Minute Timers - Stay Focused, Enhance Efficiency, and Improve Time Management - [Gift-Ready Packaging Included] by Heidi Smith

These timers look really great as numerous reviews show. And after three years, mine still looks good, except that the 30-minute timer now has a kind of lock on its neck that won't budge. Sand can still fall in the middle, but at an uneven rate, and half the time it stops altogether, as shown in the picture. The glass structure is still solid so I can't figure out how/why the blocking happened - which is a real shame as I've used both timers regularly so far. The five-minute timer is still running, so that's quite something.
