It probably works fine if you action is high enough to get this in without scratching your guitar. So it wasn't a good fit for my takamine

I love these - they're far better than the Planet Waves and Kyser humidifiers I've used before.

Be sure you measure the size of your sound hole in millimeters before you order as there are different sizes. Mine fit perfectly and seems to work well at a price much lower than some others I've seen. I'm happy!

My sound hole is 103mm exactly. The package said 100-103mm, however it is way too small. I have to use a cloth folded up to keep it in place while cased. Not worth the hassle for me to return it, but might be a game changer for some.

Be sure you order the right size it was big for my ooo15 martin guitar but fit my taylor 814 ce perfect. It's a comfort for maintsining humidity in my dry northeast home. Good price. Doesn't need much attention. Easy to pop in and out. Looks don't much affect the esthetics.

Looks good - instructions are only in Chinese. Other options for the same thing cost less.

All of my guitars are dreadnought size and it fits perfectly. I like how it seals the moisture inside to protect the wood from dry humidity issues. Great product!
