RETICLE SPECIFICATIONS:
EOTECH’s unique reticle patterns are a critical to delivering fast target acquisition and MOA accuracy at any range. EOTECH reticles feature a 68 MOA ring surrounding a 1 MOA center dot allowing the shooter to quickly pick up and lock on a target.
EOTECH One Dot Reticle
Our most popular reticle offered, the 68 MOA ring with 1 MOA dot provides three usable aiming points. The aiming points above are based on the following load: .223 cal. 62 gr. 2,900 vel. When using other loads and calibers, the operator will have to establish the ranges associated with the aiming points. When using a shotgun, the 68 MOA ring can be used to represent shot patterns but will vary based on choke and shell selection. For ordering this reticle, the model codes will end in -0
RANGE ESTIMATION WITH UNMAGNIFIED HWS
The standard ring found in most reticles equates to approximately 68" (5'8") at 100 yards.

A better floss
The wife loves this. It does remove more plaque than other floss. Its woven so it appears to grab more gunk and plaque. It is also thicker so it fits tighter between the teeth. Good product and worth the $. Would recommend.

Floss itself is great, dispensing unit is a pain
I like the floss, as it’s relatively thick and has a tacky feel that I assume helps remove material on the tooth.
But man, did they over engineer their floss dispenser. Have to simultaneously pinch two small recessed levers to pop open the case which is nigh impossible if you bite your nails. Then have to remove an inside cover, then thread floss, then carefully snap it all back. It’s so intricate that you have to download a PDF via QRG to understand it.
Compare to Dr Tungs floss where the dispenser is cardboard and you’re good to go after folding one flap.
Continued use will depend on whether my wife can use her nails to operate the dispenser unit to refill.

Works well has plenty of pressure.
It is a great device, a bit awkward to use over a bowl sink, but with some minor adjustment of the nozzle, it works well. It appears to be as effective as most water picks and I like not having to fool with a hose, that can break.

Needed replacement, 2nd one works OK
The first one I received had a broken latching mechanism. Not a shipping issue, as the box was fine, it just wouldn't latch the attachments because the mechanism wouldn't come all the way out. After getting a replacement the 2nd one worked better. It has 3 settings for soft, normal, and pulse. For me, the normal put out the best force for clearing out bits. After washing with it for about 30 seconds though I still don't feel it cleans we well as real floss, or even a waterpik, but it does help after brushing. I will add it to my routine as it does help flush out some things, but it won't be replacing my flossing. It is sort of portable, in that can be packed away and holds a charge, but it's still pretty large and takes up a good amount of space in a toiletry bag. It's not bad, but not really outstanding either.
