I hesitated to order this article to some very negative reviews. So I was pleasantly surprised to receive an article that proves excellent quality, both in manufacturing quality at the level accuracy. I use it for 3 weeks now and this is what I can say: - The plastic casing is solid and of good quality, as well as the LCD screen is very readable - On the screen and the article in general, its size is quite large, which can be an advantage (readability) or bad (space) according to individual wishes. FYI, dimensions: HxWxD = 70x125x20 mm. - Accuracy seems appropriate: difference 0.5 ° C with another LCD mini-thermometer purchased at Leroy-Merlin and measured relative humidity comparable (+/- 3%) with that measured by a humidifier Zibro D510 / D512 ( available at Amazon) - Last point: This article is powered by one AAA battery (not included). This is for me an advantage because these batteries cost less than the "button" batteries and can use rechargeable AAA batteries cheap (I use a rechargeable AAA battery with this product for 3 weeks I had not even recharged before use and I have not yet had to recharge, this article seems to consume very little current). Conclusion: I am VERY pleased with this article, I think I'll order another view of the extremely competitive price!
PS - Several vendors offer this product, I bought mine from "FirstTech".
