It took a week for the seller to send the item. The delivery arrived on time but the probe had a small dent in the part which should float. I filed a dispute and seller wanted to give 0€ back. Aliexpress finally decided 15€ return. I gave the broken device to a friend and made an order for another probe. The seller is good-hearted and does deliver top quality goods. I wish he packs the items better in the future!
Very fast shipping, good quality.
