I have Included two pictures a before and after not the greatest as there was no natural light but it does definitely work very impressed.
I cleaned all my silver jewellery Including my pandora bracelet and I'm suitably impressed. It is quite small but it's perfect for a few bits of jewellery.
I brought an actual cleaner and used warm water not cold but the results are brilliant I was dubious.
The real test will be my dog grooming blades that get filthy.

haha it's very a great tool to monitor CO2 level at home. We put it in bedroom, and it's good to know CO2 status. It can also monitor humidity level which is fantastic

The wife uses it all the time.

I use it in the car. It can detect the air quality in the car in real time . If the carbon dioxide in the car is too high, it will sound a warning sound. USB charging can be charged directly in the car.

Perfect. Just as expected. Easy to read.

Accuracy seems reasonable - aligns with my desktop monitor. Easy calibration. Not super tiny, probably too big for a keychain but perfect for a belt loop.

This thing works with ease! I’ve never used one before today and I can say it’s super easy to use!

This is a pretty good printer ... I got it for my daughter who is trying out tattooing and she hates doing stencils by hand ... It was easy to use. The stencil came out clear even the small lines that are hard to get by hand, highly recommend.

Great printer

actually I don't need this product. but because the product I was using was broken, I end up buy this product. but before I buy this product, I first see a review from a previous buyer. whether this product is worthy of my purchase and it turns out that the previous buyer review are pretty good, making me even more interested in buy this product.
when I bought this product. I'm thinking whether this product is better than my previous product. but I think positively and I'm sure that this product will make me happy and better than the product I use before.
when this product arrived I was very satisfied with the results.

Schönes, handliches Gerät mit Akku für ca, 20 h und 5V-USB-Dauer-Ladegerät. Die Genauigkeit und Empfindlichkeit auf Co2 ist sehr gut. Auch die Temperatur und Luftfeuchte wird genau angezeigt.
Ein kleiner Nachteil ist, dass es keinen akustischen Alarm zum Einstellen und keinen guten Montagebügel zur Wandmontage gibt...

Fonctionne parfaitement. Il convient de le recharger tous les jours.
Données intéressantes à la fois d'un point de vue domestique et "public".
Je l'ai apporté au bar où nous avons l'habitude de prendre notre café le midi. Même pas particulièrement bondé, on était à >1200ppm. On a mis le bar en courant d'air pendant 3 minutes et on est redescendu à 800.
Tous les endroits clos publics devraient être équipés de ce genre d'appareil

Works perfectly, does exactly what it's supposed to do! No complaints here. I've only been using it for a while and my hands are soooo much happier now that I don't have to trace or draw on stencil paper anymore! I can send my drawings straight from my iPad to my printer (Epson ecotank) with Epson iprint and after it's printed, I just send it thru this thermal copier with some stencil paper and boom. Easy peezy stencils! Make sure you get yourself some "stencil stuff" and make sure the skin is 100% clean and DRY before starting the process of applying the stencil. Five stars for this machine and I'll update if anything changes in the future!

Ive been tattooing for a year now and I usually hand draw all of my stencils but I have to say that the accuracy of using a machine is definitely worth getting a much neater tattoo. Especially for lettering. Invest in yourself, trust the process, CARE about your craft.
