Great customer service follow up and fast delivery.

Lightweight and portable. It is just right for my long-distance module transmission tests.

Packaging, delivery, and price are all good.

FS.COM shopping is very convenient, I like the UI style of this website.

The attenuator is very easy to use. The last time I tested the module, I forgot to buy the attenuator. I bought one this time. Very good product.

Last time I only bought a small batch of modules and it was very good. So I tried to buy other accessories at FS.COM, these accessories are also very good products.
