A little stretch, a lot of comfort
Just what I needed to get through long work days wearing a necktie. Expands just enough for more comfort, but still looks great, not like being unbuttoned.

My missionary loved them
My son loved these. He got them for his mission and the top button of his shirts are always tight. But these were a game changer for him.

Does the job! Easy to use
I was a little hesitant about buying these initially as the most helpful review at the time stated that they're fairly difficult to put on, but I was time crunched and another reviewer had mentioned that these shipped fast. 1. They do ship fast! I received by order in 2 business days. Greatly priced too. 2. On the second point of putting them on, I actually didn't find them too difficult. Given the design of the extenders, if you loop them through your collar button before putting the shirt on, it was super easy. The backs are wide to allow for a stretch 1/2 size around the neck, as stated (can push to 3/4 if you really stretch). Once you buttoned everything in, the slight tension helped to keep everything in place. You just need to make sure you put the extenders on before fumbling with the shirt. Button on the extender itself was pretty easy to button. Not super noticeable even without a tie / bowtie, but it definitely helps to cover.

Smaller than expected
These are really small and didn't work for my neck buttons. I used them on the wrist and shirt and they worked fine, though.

Good quality and works well. The elastic portion seems to be somewhat metallic and looks like it will last for quite a long time. Also, the actual bezel is quite classy, so even if it is visible it looks quite nice I recommend

The product works well but just doesn't stretch as much as I expected, however loop 2 together and it works very well.

The extenders are wry difficult to fit into the shirt button holes and are essentially useless.
