SWISSELITE Hourglass Sand Timers - Biloba Hourglass Sand Timer Inspired Glass/Home, Desk, Office Decor (8.5Inch-60Mins Blue)

I purchased the Blue 60 minutes hourglass and it is as advertised. Very nice and clean, the colour is well saturated. I tested the time and my hourglass runs for 54m56s - close enough for my purposes. My intention for my hourglass is to time my coaching sessions - so this is perfect. :)

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.

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.

Update: Just bought a second one, equally well-made and attractive, and likewise acurate within 20 seconds in an hour. (That's better than some watches I've owned!)I'd drop half a star, if possible, for the dust that clouds the top hemisphere when all the sand (actually, glass microbeads) runs out. It's fairly minor, barely visible in diffuse lighting, and comes down with a few taps. But seems unnecessary if the "sand were air-sorted or something. ~ ~ ~ ~ ~More solidly made than many others - robust enough for real-life use, not just as decor. And the one I bought keeps *exact* time: 60 minutes and 1 second, where others are off by ten minutes or more. Well done!

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!
