I was dissatisfied with the ckpsms goods despite being an expert in DIY. Despite their claims to offer high-quality products, the ones I bought were poor and readily broke. Even though the rates were reasonable, it wouldn't be worth it if the goods didn't hold up. In addition, when I attempted to contact customer service, they were unresponsive and unhelpful. I won't do business with ckpsms once more, and I advise others to be skeptical of their assurances of quality.
