It works properly for 20 minutes and above. Build quality - okay. I don't know about other analogues, but this one rings a little before it reaches 0, that is, at around 2 minutes approximately, then it turns a little more and stops.

It works properly and hits on time! The 4 stars because it doesn't hit in the 10-minute mark! It needs more time! So, whoever puts it for 5 minutes to see if it works will be disappointed and will think it's broken, but it's not true!

It is exactly what I expected based on the description and given the cost.
Reliable, accurate measurement, beautiful design.
