first impression when i unboxed it was great—it felt solid and ready to use right away. delivery was quick, which i appreciated. as someone in healthcare, i need reliable tools, and this one nails it. it's very plug-and-play, just turn it on and it works. i've used it for checking water quality in my aquarium and it's spot-on. being a brand loyalist, yieryi didn't disappoint. overall, it's a fantastic gadget that makes my job easier.
- Pros: the accuracy is very impressive, making it easy to trust the readings for my work. i love that it connects wirelessly, so no messy cables to deal with. it's super versatile and handles different liquids without a hitch, which is a huge plus.
- Cons: the price was a bit high for my budget, but it's most likely worth it for the quality. sometimes the connection can be a little finicky, but nothing major.
