4-18" Inch Armband 360° Adjustable for Dexcom G7 : Transmitter Protection Sensor Cover Arm & Leg Band -No More Adhesive Patches (4-18" Active Band Black Matte)

My husband is thrilled with this, he enjoys working outside in the FL heat & humidity (so he sweats & the other "waterproof" stickers we have tried did NOT hold up). This one is actually designed by a Veteran, my husband is also a Veteran & he appreciates the flag being a part of the design. It's also adjustable & reusable over & over so a true bargain! It has easy to read & understand instructions & is going to save us money in the long run, all the while working better than anything else we tried. Truly appreciate this & it's adjustability means it' comfortable to wear 24/7 if needed. Thank you for this amazing product!!

First band I’ve ever tried.The band fits okay, not bad. Could use a few improvements. Make sure not to tighten too much, it will cut off circulation and cause problems with nerves. Even with the band a little tight, I feel I have to reposition the band too often still. Not good. On the plus side, sensors haven’t come off, when I thought they would.The frame that fits over sensor lasted 26 days before breaking. I believe that is not good, for the cost.The first sensor I tried with the band, I didn’t apply the over patch that comes with it; which for me worked to hold sensor on, but I always had to wear the band, because the adhesive on the CGM somehow worked its way under the sensor.The frame broke after 26 days of use. Hopefully, the frame from the second band I bought will last longer.It only happened once, on the last night, the band/frame popped off the sensor, during sleep. The band unvelcroed/unfastened. The frame came off the sensor; which isn’t that easy, so not sure how, because like another reviewer said, put a little pressure on CGM to pop off the frame. I didn’t think to take a picture. The edge of frame was under the sensor.I feel this product could use a few improvements; otherwise, for my first band, it’s not bad. I would recommend, but it definitely needs an upgrade.

First to counter the people who complain that this won't fit the Dexcom 7 because the Dexcom 7 sensor isn't round like this holder is: it does fit. It doesn't snap, nor does it need to. When you apply a Dexcom 7 sensor you can never be sure if it will apply upright or tilted. The circular opening of this holder is the perfect diameter to surround the outside edges of the Dexcom 7 sensor, regardless of any tilt. It was designed that way.Second, do scan the QR code to see the instructions of how to adjust the band size. There are two fabric loops. For arm wear, you need to remove one permanently. Once you do that, you will find that you have much more flexibility in size (especially the people who complained that it was too big or inflexible). Only if you have huge body-builder bicep muscles you might have trouble with one band not being long enough.If you find the band itches or makes a groove in your flesh, just start wearing it a bit looser.When installing or removing the band hold your upper arm parallel to the floor so that you are not fighting gravity. When removing, 1) pull to release the velcro 2) Very important: place a finger through the center hole of the plastic holder to separate the holder from the Dexcom sensor (it won't be snapped in because it doesn't snap but this step relieves any friction).Twenty dollars seems expensive for this, but it is very much worth it. In five months of using these bands I have never had a sensor to fall off or get bumped off scraping against a door frame. I have never had to call and ask for a replacement sensor. I bought a second band so I can shower with the band on, remove that band, replace it with the dry one, and then hang the the wet one to air-dry for the next time. I'm sure the velcro will wear out eventually so I am going to buy two more bands just in case these ever become unavailable. I don't ever have to spend money on disposable adhesive patches and I am spared the pain of tearing off those larger adhesive patches along with my arm hair.

The band provides some confidence the sensor will not scrape off. I place the sensor on the back of the upper arm, high enough that the band almost doesn't fit. It becomes a fashion statement.There are two straps with hook ends to mate with the loop straps. The straps are so long that for me they only mate at the very end of travel, which prevents me from tightening the band to taste. The elasticity of the band is somewhat wishful thinking, therefore.If you have wider upper arms, you're apparently the target audience.

It is adjustable but even at the smallest size it is still way too big for my arm and I am 6'2 205 lbs. Unless you are a professional bodybuilder this will not fit you
