It works, but its very tight

The strap is pretty universal, if nothing else than it does not actually attach to your rifle.  You tie it to the barrel and loop around the butt stock, using the face guard on your rifle to keep it from sliding toward the trigger.  With the strap fully extended it is a tight fit to carry it on my shoulder.  I bought two of them for two different pellet rifles (Remington NSS and Gamon Recon) and the NSS, being larger, is a very tight hold.  I wish they would have added about 6 more inches of adjustment.  The strap pad is also pretty thick (approx 1/2"), which I find to be more of a nuisance than a positive.

It works, but does not fit snugly into the port, so it falls off of the chromebook at the drop of a hat.

It works great, just wish it was a little larger.

Works fine, but for some reason it was a little to snug.  I had to push it in kinda hard to make it fit.

it is very good, but i guess it is too tight, although they only have 1 size and the X small... the normal size is too big, and the xsmall is too small... but after all its a good product

Pro:
Fits the speaker well
Carabiner is strong. Held up while it was on my pants loop and washing big outdoor windows
It doesn't muffle the sound too much

Con:
Because it fits so tight its hard to get to the buttons of the speaker.  I have to pull it out a little, which isn't easy because its so snug.

This spring was way way too tight at first and would slam shut. Now it's loosened up a bit, but it's still pretty tight. It gets the job done and I'm thinking it might ease up even more over time.

This is a little bit tight to my earphone, but with a little streching it works.

It does not fit perfectly  but it does the job. Band its to small

It works, But it's a little too small. It gives the effect that I wanted, But it makes it too hard to breath at times, And it cuts at my arm pits. Next time I order I size larger, Especially for those who have a larger body structure.

Its a pretty tight fit if you actually want to put cards in the slots. But I guess it gets the job done. I'd rather spend my money on something a little bit better and bigger

It works, but it is hard to seat the micro-USB all the way in and you don't feel the "click".  I have used it on multiple micro-USB devices and they all felt the same "tightness", so it's not the issue with the device.

Its very amazing it is very tight so it takes a while to put on the phone but it is good.

I can use it, but a lot smaller in than the picture

When putting my phone in, it was such a snug fit, which made it hard to take out. But it works for my phone.

Works, but the money clip part is so tight its hard to put cash in it, or pull it out of it.

It fit as expected...it is suppose to be tight for it to work.  I will say this, it is uncomfortable but if you want results you have to deal with it. If it is too loose, it will not work.
