SWISSELITE Hourglass Sand Timers, Hourglass Sand Clock Inspired Glass for Home, Desk, Office Decor (8.5Inch-60Mins Oil Yellow)

A very good value for an hourglass.I love the size, shape, and color.The "sand" is actually very small glass beads, like that used for sand blasting or sprinkled over wet paint to provide reflectivity. This is a good thing; greater uniformity in size and less likely to get "stuck", as other hourglasses sometimes do.A small amount of sand will stick to the glass. A gentle tap will loosen it and it falls through in about a second, so it doesn't affect the accuracy.For the 60 minute hourglasses, the seller claims an accuracy of +/- 6 minutes. That's a pretty wide range; probably 2 or 3 times the actual variation in run times. I measured 1 hour and 22 seconds (although the exact time may be temperature dependent). I got it for the aesthetics, not an accurate time peace, and I am very pleased with it.The seller said the glass is borosilicate. This is the same type of glass as Pyrex (TM), and is used in glass coffee pots. It appears to be solid and well made.I liked it so much I ordered a smaller 30 minute glass to keep on my desk at work.Verdict: BUY!Update 1 (a few days later): 30 minute Rose Red color hourglass [https://www.amazon.com/gp/product/B078H82WWD/]. I give this 4 stars; docking a star because a small (but quite noticeable) amount of sand clings to the glass when running. Runtime measured (once) at 30 minutes 6 seconds. Remarkable.The sand clinging issue may be related to the coloring added to the sand (really, very small glass beads). I ordered the 30 minute white sand hourglass in the same style to see if the sand without coloring has any issues sticking to the glass.Update 2 (a few more days later): 30 minute White color hourglass. Solid 5 stars. I ordered the 30 minute glass with white (uncolored) sand to see if the color affects how much sand sticks to the glass. I am happy to report that only a little sticks to the glass (much less than the Rose Red color), and it is easily dislodged with a gentle tap.

I've had hourglasses before (but not full hour) - this isn't my first rodeo {i'm 65, i've been to Every rodeo} But this is the nicest one i've ever had. It's off by like 4 seconds - crazy close.Going to make a wood cup for a base with a rubber lining - you've seen em.It's a Beautiful shape. Helps to keep my mind from wandering {65 remember} and cutting practice and studys short.Just might get another one in a different color, or a half-hour one.

Cute. Although larger (sturdier?), I have several others in my office that have been durable. This one fell once and broke.That said, it was an easy clean up! The sand stuff stayed contained on one side and it split cleanly in half.

Perfect ! I enjoy this hour glass, approximately an hour.. I have purchased 2! One for my fiancé and brother.. I also have one purchased previously & use it at my work desk

I bought this as a visual reminder to take the occasional 15 minute break at work. The timer is a good size and I like the blue sand color. It's also pretty accurate....coming in at about 9 seconds under 15 minutes.This is a fragile item. If you knocked it over on any hard surface, I'm not sure it would survive. If you are careful with this, it's a cool item. #noplastic

Bought the blue one hour version, as a medication I take requires a 60 minute wait before eating! I always forget to look at the time on my phone and this hourglass leaves no room for error and looks interesting on my table and is fun to use! It is so accurate - just 4 seconds over one hour as compared to my iPhone stopwatch! Love it!

The one on the right is from the order I placed in February and the left is one I just purchased in April. They are now bigger and the sand is a darker more saturated shade of green. I was expecting these to be the same as the original order I placed and now don't have time to order new ones which is really frustrating. There was no indication that the design had changed.They're still cute but I wanted then all to match for the project I'm working on with them. These new bigger ones are still pretty nice but I noticed the sand sticks to the glass a lot more which is annoying.

Bought 60 minutes version. It lasted 59 minutes and 34 seconds, which is pretty decent. Good way to keep focus on the task. Packaging is done by styrofoam shaped to fit the glass to keep it from shake/break. Delivery ran late which was regretable. So much for "prime" shipping.

This item is perfect and exactly what I wanted and it came earlier than expected.

I love the look of the hourglass. It is very elegant looking. Calming to watch the sand shift and is a reminder to me of how finite life is.

I got these to remind me to value the time I have with people, I don't use them to time anything and don't know if they keep good time. I like them.

I bought it just as a decorative piece and love it.
