I bought their guitar strings and was dissatisfied with the quality; they snapped easily, and the sound wasn't as good as other brands I've used before, despite their claim to be the industry standard for guitar and bass gear. Additionally, when I contacted them to express my discontent, their response was unhelpful and unsympathetic; they didn't appear to care about my issues or give any solutions to the issue. I would not suggest their items to other artists, and I will be seeking elsewhere for my gear in the future. Even though KAISH claims to be the greatest in the business, their products and customer service left a lot to be desired.
