Review: Small, simple and gets the job done. - Their is nothing that I don't like. Very easy to use, seems accurate enough for field work and can easily slip in a pocket or use the case that comes with it.
Review: Quiron handheld Optical power meter - This little meter is just -1 off than my $$$ big Optimeter... when I'm climbing poles and need to hook up fiber drops, it's so much easier bringing this small item than the very large and pain in the @#$%& Optimeter. So when I know I got light, I'm good to the slacknid at customer prem then the FJ. Definitely easier to use. This gives me ready within 5 seconds turn it on. While the large OptiMeter takes about 3-5 minutes for a reading. So there is a -1 difference between the handheld and the large . It's negligible. Overall happy with this product. Using it about 4 months now. ****????"""""""""???????"""""""""""""""" Note: Only downside.... wish they provided a carrying pouch for your belt... but you can't have it all
