Harley Benton NeckWrap Small

I got small and medium size of those and I was surprised to see almost no size difference. They were both kind of small. They are very soft, which makes it difficult to mount on or to remove it quickly. They are black on the photos but what you cannot see on the photos is that they glitter if there is a direct light put on it. So, having it on stage will make it pretty visible. Some people will like this, some other like me - not so much.
The other product by GruvGear is made better but both of them are ridiculously overpriced.

Handy little damper that I use in my little home studio to stop guitars from resonating while I sing or record percussion. Place the damper in the middle of the neck and it works great. I bought the small and medium and advise the mediums for acoustic guitars.

Super useful tool for dampening open strings, fits properly the regular 6-string electric guitar or 4-string electric bass. Awesome item.

I use it on my bass and it works much better than a hairband, can't complain at all.
Fits well on a 42mm nut neck, I would probably go for a larger size if your guitar/bass has a wider neck, if you're not sure then go for larger because it has velcro straps and is pretty adjustable.
Nothing sharp or scratchy on it so not an issue on painted/finished necks.

Pretty cheap compared to other like gruvgear, Does it's job.
When im not using it to practice solo parts it works pretty well on the headstock to get rid of headstock harmonics.
Can't really speak for durabilty, probably depends if you slide it on/off or if you are meticulous and open/close it before moving it from the heastock to reduce wear.
Would buy them again even just to leave them on the heastock.

It does what it supposed to do, but I'm not sure if it will last for a long time. The fabric it's made out of does not feel too durable.

Simple product that does what you'd espect

nice quality and works well i use them mostly to stop string ring and they work great. much cheaper than other brands and is good quality highly recommend if you’re looking one but don’t want to pay outrageous money

The sizes are to small so I am "glad" I bought one of each but the smallest doesn't really work on my most narrow 6 string electric guitar neck. The velcro /fitting are too short. And the damper part seems also short. And material doesn't dampen well. Need to fiddle around with it alot to get decent results. I had prior the cheapest I could find on Ali express that costs less than a tenth of these. And sadly it is many times better..

Not small, not big, that thing ideal
