Me quedó PERFECTO. I wanted a shoe that was tough, comfortable all day, waterproof, but also didnt look like a work boot. A minimalist sole. I?m hoping they update this as the system matures. It holds 9 spices per level and I love the adjustable shelf amount and that I can place just a couple together and separate them around the kitchen. Use a blunt knife or screwdriver to pop out the plastic end bit inside the slider part of the headband, then slide the old head band cushion out, slide the new one, and clip the plastic end bit back in. It took me about 5 minutes to assemble and it came with the allen wrench to tighten the screws. I lock the zipper pulls together with a small padlock. The belt is very easy to use and takes some dedication to be consistent in using it, but I have extremely happy with my purchase. I recommend a socket set or box wrenches along with an adjustable wrench or "Channel Locks.
