I have two scales that work relatively well, but have there limitations.
I have an OHAUS LH200 scale that I use for my larger leos...only problem is that is measures in ounces. But converting is easy as can be. Or I could just type in "2.23 ounces" into google and it would provide me with the weight converted into grams.
For neonates, I use a large-pocket-sized ACCULAB PP2060D that does a great job of of measuring in grams of weights up to around 50 grams.........only problem is it doesn't provide much room for the gecko to "stand on", hence why U only use it for hatchlings and juveniles.
There are obviously better brands and models out there, but I got these for free so I'm not complaining.
I'm sure other people have hassle-free scales that are much more convenient.
