Great quality product, no Giardia yet, and I live where it's endemic. I keep a few in every backpack, daypack, first aid kit, vehicle, and bug-out bag.
Ryobi Phone Works Inspection Scope ES5000 New
05 juin 2017
Yesterday's technology at tomorrow's price
There are similar items for around $10 now. Besides the price, my specific issues with the ES5000 are:
1. The Android app is a little hard to use, and must be downloaded to each device you want to use the scope with. Not such a big deal unless you're on a job site w/o internet access. And if Ryobi ever pulls the app off the Play Store then this expensive tool just became a green paperweight.
2. The lights aren't very bright, even on high you can only see about 3-4 feet in a dark space.
3. Kills AA batteries fast, less than two hours run time on new Duracells
4. This the big problem for me, it connects to your device as a wifi network, not Bluetooth. This is a pain as you have to set it manually on your device each time you turn on the scope and you can't be connected to another network at the same time.
