I have always been treated and serviced with whatever I needed from FluxLight. They are professional and courteous at all times and very easy to work with.
This works perfectly fine with HP switches and has a better price point!
We install these in HP and Ubiquiti gear. Always works great, we have bought hundreds over the years and I can't remember ever having a problem with one. They are a fraction of the price of the HP product and work just as well. Highly recommend!
I called FluxLight to makes sure I go the right one. They were very patient with me and we got it right on the first try. The device works perfect. We have been up and running since installing with no problems. We ended up buying more later and all devices have worked with no problems. You can't beat the price, service or the speed of delivery.
The receiver works perfectly and you can't beat the price. I called to make sure I got the right one. Fluxlight got me set up over the phone and within a few days we were up and running. We won't buy from anyone else now.
A+
Every SFP I've purchased from FluxLight works, just like I expect, just like it should. I have been very pleased with their performance and will continue to purchase and recommend them.
Por el momento todo bien, graciads
I received it on time as scheduled. Once I used it, i will make a follow-up review. Thanks a lot.
