CarsonTriView 5x/10x/15x Folding Loupe Magnifier with Built-in Case, 3-in-1 Portable Loupe Magnifying Glass - Adjustable Magnification, Great for Jewelry (TV-15)

The wider lenses on this hand lens was amazing to use as someone used to the really teeny standard hand lenses. They were super clear and have held up quite well even after being used regularly in the field. I've dropped it both opened and closed and I've cleaned it a ton and no scratches (at least none yet).

Very useful. Reasonably well made. I'm not sure how this compares to a $150 piece like from Zeiss, but for the price, hard to go wrong. Lenses are clear. Convenient size.

Good tool. Instructions would be helpful. Simply the lenses magnifying power are increased by adding more lenses. One lens equals 5x two lenses equals 10x and three lenses equals 15x. The limiting consideration is the size of the effective field of view.

Love it. better than I expected/

The perfect answer for the antiques business, examining and identifying marks. An essential for success. Compact, sturdy, does the trick.

After reading the other reviews I thought it was my error so I tried using this magnification device 8 to 10 times and every way. You have to be REALLY close to the item to be magnified and then the "fish eye" look made the very small center to be larger and clear but 50% of the out part blurry. If the other reviewers can educate me on how I'm using this incorrectly, then I will update this rating and review.

Each lens is great and has good edge definition. I wouldn’t use them in conjunction though, it narrows the field of view too much. But 5X 10X 15x are the most useful magnification for looking at overall bud development. I’ve found higher than that has too narrow a view and is useless for telling when to harvest.
