very good and easy. also seems to measure very accurately. the charger is usbc which is nice as well

Awesome product great quality. It arrived earlier than expected. Exactly what the description says.

It's much better than I expected. It has different timer modes and its response time is very fast.

They work instantly and really well. A fraction of the price of the same thing on Amazon.

Love it – such a fan I even bought one for a friend. Best value for money on the market
