Excellent product.  I am using with my amateur radio for emergency communications.  Excellent sound quality.

I paired this with an RCA signal amplifier (under $10), mounted it in a window on the second floor (indoors) and am now receiving all of the broadcast channels available in my area.  This after spending about $150 combining (using an antenna coupler)  two Leaf flat amplified antennas in the same window in the same position and getting less than half the channels available and never without problems.  I am very pleased with this product.

Excellent product.  Setup was extremely easy and fast.  I was able to extend my network to a couple of weak spots in my house.  Also the overall signal strength in these areas was very strong as compared to not using the extender.  I was able to get my network to extend to both my front and back patios so I could easily work outside.  Great price for a  very useful product.  I liked the fact that I could add some devices to my network by use of the 5 Ethernet ports and the USB 3.0 port.  I am using this AC1900 WiFi Range Extender in combination with my Netgear R7500 Nighthawk X4 AC2350 Dual Band WiFi Router.  This is an excellent combination to maximize my WiFi network.

Excellent product.  I used this adapter for my in house FM transmitter.  No hum and works prefect.

Just tried out the wireless microphones.  LOVE IT!  I'm using it on a Canon VIXIA HFR3000.  The sound is clear and the lapel mic can't be beat for the price.  Thanks Azden, this is a quality product.

The wireless transmitter and receiver are easy to use.  Just throw in a 9V battery into each, flip the switch and away you go.

Excellent product. Easy to install. It does what it is described to do. Very fast and steady connection. Goodbye to wireless adaptors.

Excellent product. Appears to have a good solid build. Enabled us to pull in a relatively weak wifi signal.  Very satisfied with product.

Just got my tech licence for Amateur radio.  This radio is extremely feature rich for the cost point.  I can hit all of my local repeaters with the stock antenna and get great signal reports!  Recommended.

Sain Store provided prompt shipping and the product met my expectations.  This radio is probably the best "Bang for the buck" I have found in Amateur radio equipment in years.

Excellent product. People can hear me clearly when I drive, no complaints about road noise from the people I call. Connects super fast to the Iphone.  I'm still learning this but I am so glad for finding this bluetooth device.

Excellent quality product.  Well built, works well and looks good.  Unit amplifies the phono input only.  Unit does not amplify the other inputs but does control their volume from 0 to 1.

I am using this product to connect my phone, via bluetooth, to the Auxiliary Input on my car.  Overall, this is a great product.  The sound quality is excellent.  My only complaint would be having to press the button on the unit to reconnect to my phone.  Ideally, upon power up, the unit would automatically connect to my phone.

Work as expected, even in my ham radio RF field environment, would buy these again!
