I rarely write reviews. But I did want to say I had zero luck getting this to work on a mikrotik crs309. I will say though they dont have mikrotik listed anywhere in their description or photos, I took the risk based off of other reviews and it didnt plan out. HOWEVER I will still give this 5 stars based off other reviews for manufactures that are listed & the solid price. tl/dr: Didnt work with my mikrotik gear, still seems like a solid product.

These are great SFPs at a great price! But in addition to that, I want to give major kudos to the 10Gtek support team. We made the mistake of selecting the wrong variation of SFPs for our switch. It was our fault, not theirs. Nonetheless, their customer support team arranged for us to send them back in exchange for the correct model! They had no obligation to do this as we didn't realize our mistake right away. But unlike so many other companies on Amazon who will find any excuse to not support you, they went the extra mile to help us resolve the issue we created! You really don't find that much any more. Plus, the agent I spoke with communicated very clearly (important when technical details are critical), which is also uncommon these days. So I wanted to share our experience of excellent customer service by the 10Gtek team. That speaks to a company who has the right focus--the customer! We will continue to buy their products, that's for sure.

At this price, thought I would try it out since my US-8-150W has those 2 SFP ports I don't use. Well to my surprise, and still unexplained, I actually get a better transfer rate from these than the RJ45 ports!? Would 100% recommend.
