I have three of these devices now. They work great with the rlt-433 software running on a Raspberry Pi zero W.
The plastic case does not provide as much rf isolation as the devices with metal cases, but for my purpose they are just fine for half the price!
It should be noted that the six-inch jumper has an F-connector, not an SMA.

For those of us who are just learning how to use these, some instructions to set this up. As of this review I still cannot make it work.

I have used this device to help users setup a small ADS-B and can't recommend this enough.

Was curious if this would work with Piaware, as this device is much less expensive than the branded one from Flight Aware. This does work with piaware! Just follow the instructions on the flightaware/piaware site for installing the software/drivers, and it picks up this device. I didn't have to do any special config or load custom drivers. The included antenna works fine for me.

Plugged in and worked as advertised, even in bad location of house
