    What really stood out to me was their customer support. Even though it was my first time ordering and my purchase wasn't huge, the sales rep was super friendly and genuine. They took the time to ask about my switch model and connection needs, and recommended the Cisco-compatible version. The optics worked perfectly for my project.

    I bought it on a whim at first, and honestly, I didn't expect it to be this good. It works really well with my device, so I’ll definitely buy it again.

    I have purchased several times from qsfptek and am very happy with the pricing, customer service, and product. The customer service was really good and patiently answered my questions. However, I find the website is not that convenient. Sometimes I just can't find the model I want to buy.
