4 Pcs Diabetes Arm Band Diabetes Sensor Cover Washable Reusable Diabetic Sensor Armband Sleeve for Diabetic Supplies Sports (Small/Medium)

Size for sm-med ran to big so my husband used two of them and I sewed a new seam to make mine smaller. We like them better than sticky residue from patch covers. Quality is good, comfortable and looks better than patches that shift and leave glue on skin that's hard to get off. Easy to use and a great value for the four pack.

These thing are falling apart after only a few uses. The stitching is coming undone and fraying. Also, the largest size is still too small. They have been great for holding my pump and Cgm on during workouts, but it’s so tight on the arm it leaves marks. I wish I could return these and get some bigger, higher quality ones.

I think I'm going to prefer this band over the straps I'm currently using. The straps sold by Amazon are good, but the velcro eventually starts hanging on shirts. This band has no velcro so hopefully won't hang. Either straps or this band will protect the CGM sensor. Never have lost a sensor with the straps. Guessing this band will work better. Check with me in a year.

I measured my biceps, both un-flexed were right at 13 inches. I looked at the sizes and picked large, listed at 13-14.6 inches. They arrived the next day, compliments of living near many Amazon facilities. Unfortunately that's the only good thing about this order. I toss and turn from side to side a lot when I sleep. Basically sleeping on one side until my shoulder screams, rolling over to the other side. Rinse and repeat. It isn't my CGM sensors' fault, but rolling over one night I ripped... No I drug the sensor across and out of my arm at 3am. Let's just say it didn't feel nice and I'm not prescribed extras so I can't be replacing them early too often. I ordered these to hopefully help protect the sensor, which I feel they do. Unfortunately, I measured and ordered the appropriate size. Only they weren't the right size. These were so tight I was getting what felt like tendonitis pain in my elbow and forearm. After just 3 days I gave up and ordered something else. Again, I was on the low side of what the Large size should fit. I'd understand if I was on the high side, but this should have been loose fitting if anything. I can't imagine having a larger arm. After coming back to the reviews before making my own, I saw another where the arm band was too big. I think this company may have a quality control problem with fluctuating size. I do recommend an arm band to protect your CGM. I just can't say this is the one to order.

This was too small for my arm. Made a big welt on my arm within the first day

Arm band fits very good. It is not tight.

These arm bands work great. I wear it at bedtime over my sensor so it won’t get knocked off during the night. I bought the small size, but later bought the medium/large size and it fits better and not so tight and more comfortable.

Great
