Happy Customer!

"I purchased these glasses for my bar area. They are perfect! Will be great for beer or cocktails. Honestly they can be used for anything. Let's talk about how they were shipped.....the most robust packaging I have ever seen!! No worries with broken glass here! Job well done. The coasters are super cute too! And who doesn't need an extra bottle opener!"

Perfect for Guitars and Bass Guitars!

"I've been using several types of these self closing/locking hangers for a couple years now - on stands,dual stands and wall mounts supporting everything from ukes to homemade cigar-box guitars to classical jobs. Although all have worked fine this is a heavy duty version of the same - suitable for electric bass and full-size electric ... you place the headstock on the arms of the holder ...its weight pull-down triggers two end caps to close off the cradle, preventing the guitar from any accidental drop!"

Great Wall Hanger

"This is a great wall hanger for my bass and guitars. It was very easy to install and put together. The instructions that come with it were helpful....I have also tried it with some of my lighter guitars and it seemed very sturdy. The lock feature works very well and is very sensitive to weight. The woodgrain on the mount is beautiful. It is great that it comes in different wood stains/colors for added versatility. Overall; highly recommended."
