Review on ⏳ XINBAOHONG Sand Timer Set - 3 Minute Yellow & 10 Minute Orange Hourglass Sand Timers for Kids, Classroom, Home, Office, and Kitchen Use by Summer Edwards

I was wary as a set of two cost a little less than one from other suppliers, they arrived quickly and looked well made. They're a lot bigger than the lousy hourglasses that come with board games. They are just over 6 inches high and 3 inches wide. The colors are pleasing and they meet their accuracy goals (these are hourglasses, not precise stopwatches). Most of these products claim an accuracy of + or - 10%. My 3 minute block i at 3:06 is pretty good! and the 10 minute block ends around 9:35, still within the 10% target (within 9-11 minutes - 10%), pretty well. I want this company to make a 1 minute version. The inner hourglass is made of glass and the outer protective edge is made of transparent plastic, I recommend it.
