The thermometer is good, came in a tube, but without a battery. It fits AG13, everything works. Of course, the error in the measurement is, tried on the water, after boiling had another minute to boil water and only then the thermometer dialed 100 °.
The thermometer came in a tube, with instructions and without a battery, as in the description, everything corresponds. The battery bought separately and checked, everything works fine, it's happy! I recommend to purchase!
Got to moscow in a month. Packed not very, but all whole. The battery is not included, bought for 50 rubles. It seems to work, but when cooking has not yet checked. I'll sign this in addition. While i put 5 points. I recommend.
