I bought a Snark from Guitar Center a few years and still use it. I thought I would buy additional Snarks for each guitar and eliminate relocating or forgetting to take the tuner when traveling. This Snark is different from the original one I purchased a few years ago in the following ways. 1. The plastic is NOT the same. One of the units cracked at the back ball collet. I had to re-glue and permanently mount a cable tie to support the broken collet tang(s). The glued one held but cracked another tang during re-assembly. The original Snark is made from a matt finish elastomeric plastic. the new one is shinny brittle plastic 2. The electronics are different. It seems to take longer to find the string and indicate the correct bias. This is a minor issue. I suggest when purchasing a head stock mounted tuner you have first hand tactile examination. Snarks are convenient but are either offered in decontented versions or they have cheapened them up. Hope the former.
