amocane Sauna 15 Minute Hourglass Sand Timer, Sauna Accessories Wooden Rotatable Timer(Hemlock Wood)

A standard tool of keeping track of time when you can’t see (don’t wear my glasses in sauna) the clock outside.

Screws did not come with hourglass for mounting, but the item itself is great.

There is no real scale on the timer; I had to make marks at 5,10, and 15 minutes. They were nowhere near the numbers printed on the wood. After two weeks the sand would stop flowing at random times. One would have to flip it over and start again. Then, the sand started to visibly stick to the glass walls of the instrument. Sticky sand does not flow. This is a bad prodcut

Accurate time measurement-water/ steamproof

This item seems to be working fine. I am in the early stages of use in my sauna. However, so far so good. After some use I had a problem with the glass, but the seller did an excellent job of responding to my problem and now I am a very happy customer.
