I ordered this to use with my Walker’s Razor slim muffs, and I found it to be high-quality and offers great protection. The zipper operates smoothly and the inside lining is soft. Note that if you have a different brand that are larger at the bottom, this may be too tight. But for the Razor model, it fits perfectly. Also note that there is compartment in the lid. I use that to hold the batteries when you don’t use them for a while. If you don’t use your Walker’s regularly, it’s best to take the batteries out to avoid corrosion. Overall, I am very pleased with this case. Highly recommended.
