Perfectly adequate.
Worked perfectly well with good enough accuracy for hatching Guinea Fowl eggs in a home made incubator.

Excellent value for the money.
I have a pallaudarium where the plants love very high humidity. This does the job to tell me how humid it is in there. A simple, but excellent bit of kit.

Perfect for monitoring humidity in a vivarium.
This was really easy to install. The instructions are simple. I bought this so we could monitor the humidity in our corn snake's vivarium. I'm a first time owner and our snake is a rehome. I've been doing research and a whole lot of watching and learning habits because I went into this not knowing a thing! The hygrometer functions well. Its easy to see. It seems to be pretty accurate and the first shed was a perfectly complete so the snake must be happy.

Appearance, dial, accuracy great for beginners.
* Easy to install / use * Size is perfect enough to be read. * Accurate in temperature measurement for the most part as i've not yet seen a problem. * Value for monies without no doubt. I do have to admit i bought this in a hurry thinking it was a thermometer, only to realise it is actually a hygrometer. Beside that, i'm really glad i have bought this hygrometer as it really works a treat in keeping my little dinosaurs in the right humidy possible, without it i would of been lost and i'm pretty sure my little dinos would've thought i was a useless owner lol.

Handy little hygrometer
I have been using this to check the humidity in my incubator. Works great and seems to be quite accurate. Very easy to use, just put it where it’s needed and it did the work for you. The only thing is when the humidity gets too high it can be quite hard to read but that’s mainly because I have to have it flat, I’d imagine if you had it in a tank and used the sticky pad to secure it then it would be much easier to see. Great value and good quality. Would recommend.

Backup to digital
Wasn't 100% sure if my digital one was reading correctly so I got thos one. They both read the same so they're both correct. Very easy to use just make sure you remover the inner circle of the adhesive pad or you'll block the censor. Read a review with photos showing it not working but it was on the outside of the tank! So it works great and is easy to read IF you place the sticky pad correctly and put it inside your tank. Good value for money . Built well and reads humidity perfectly

Good Staple
I tend to use one in all my vivarium's, they're a quick reference for the humidity in them. As far as I'm aware they're reasonably accurate (being analogue and compact, extremely accurate readings aren't on the cards) Would recommend

Works and readable at a glance
I have two of these in separate vivariums in the same room. I've had one for the better part of a year and have had the other about 4 months. They have been working fine for me. I love the color coding that makes them easy to read and interpret. I don't feel the need to chase humidity down to the single percent, but rather follow trends and correct conditions as needed. While there may be times when the needle doesn't seem to move much, when the house become dry in the winter and supplemental humidity is needed, these little hygrometers help me keep viv humidity in the right range. If you need to move these they can be moved. I used a razor blade to remove, removed all the backing and then hot glued in the new position. While the included tape is relatively safe in a viv, with snakes fully cured aquarium safe silicone or hot glue is even safer. Just be careful to use small amounts of glue on the four raised pads. If you block airflow it will not work right. What's not to like about useful, inexpensive and easy? Love these.

Ich kann mich nicht beschweren
Ich brauchte für mein Terrarium mit den Orchideen schnell etwas einfaches. Das lag daran, dass das Terrarium nur geliehen ist. Ich habe etwas gezweifelt. Zum einen ist es keine unbekannte Firma und zum anderen waren die negativen Kritiken recht deutlich. Nun ich habe es doch gewagt und zweifelte den erste Tag nach der Anbrinung. Doch schon am zweiten Tag musste ich feststellen, dass es wunderbar funktioniert. Das Hygrometer reagiert sehr schnell und auch sehr fein auf jedwede Veränderung. Auch der Kotrolle durch ein anderes Thermometer hält dieses stand, sogar ohne größere Abweichungen. Hier lagen die Abweichungen aber eindeutig daran, dass das Kontrollgerät auf dem Boden und damit auf nasser Drainage stand und dieses an etwa 15 cm über den Boden an der Scheibe befestigt war. Ich kann mich nicht beschweren und für meine Zwecke vollkommen ausreichend.

Parfait
Hydromètre plutôt lisible et semble fonctionner correctement pour un prix imbattable (moins de 3€) Parfait pour mon petit terrarium! Seul point négatif la fixation se fait par ruban adhésif, j'aurais préféré une ventouse (plus pratique pour l'entretien)
