The Belomo 10x handlens is definitely a wonderful tool. A Hastings triplet design that is built like a Swiss bank vault. Optics are superb (razor sharp and bright) with a much wider field of view than my Bausch & Lomb 10x Hastings - which for entomology is a big plus! My collection of hand lenses is fairly large and I also use stereo microscopes for my work, but the Belomo can always be in your pocket ready to use anywhere and enjoy at any time. Its heirloom sturdiness will provide many years of visual pleasure. My first order got lost in the mail and the great folks at Amateur Geologist didn't bat an eye and sent another which was very kind, proving that they're definitely there to help their customers. My sincere thanks and appreciation goes out to them for their fabulous service and wonderful products.
