3D print quality wasn't the best, this package took like a week to get here. Got sent back, not the sellers fault. 3 stars because the Antenna was bent and the shell was kinda open.

1) If using this device with a Flipper Zero, it will not work with the SubGHz App. The device requires the 5v GPIO pin be turned ON so it can get power (pic 1). However, when the SubGHz App is opened and External antenna is selected (pic 2), the 5v GPIO pin turns itself OFF (pic 3) and the device no longer gets power.2) No instructions are provided with the product, so you have to rely on dubious Internet searches that turn up conflicting information. No solution has turned up about the 5 volt power problem, either.

Die Reichweite ist auf 433 MHz deutlich besser, ca. 10 Fach.Im Lieferumfang ist nur eine 433 MHz Antenne dabei, diese kann keine 868 MHz Signale empfangen. Auch mit einer 868 MHz antenne ist die Reichweite eher enttäuschend. Mit einem Garagensender ehöht sich die Reichweite nur von 1m auf ca. 2m. Da gibt es bessere Module die beide Frequenzen unterstützen, aber auch deutlich größer sind.Für 433Mhz aber zu empfehlen.

It's bulky but it handles business. Mine fell on my kitchen floor, and literally vanished. So I'm buying another.Pretty good signal range for activities.

It works great the 3d case for the circuit board is very fragile but works like it's supposed to

This works great, I can definitely see a performance improvement with it as opposed to without it, in my case, sending a signal through some walls to the other side of your house I wouldn’t be able to do that without this intense extension. Great add-on until Flipper adds a better built-in antenna.

The included antennae is great but its either not meant to come off or its on there really tight, I am nervous trying to take it off some I am leaving it on.

This is well built, the pins are long enough to fit snug against the flipper and not go anywhere but if bumped it can pop out. The GPIO Pins are solid and dont bend. The housing is a snap apart housing that appears to be 3d printed and does the job. The only thing that i would want to improve would to have the pins a tiny bit longer so it can stay snug with the silicone case on it. Or if someone designed a silicone case to support this being left on to keep it down. If you have the silicone case this thing will pop off if you throw it in a bag or pocket, so be careful. Definately worth the buy- Unfortunately i havent had much time to play with it other than annoy tesla owners.
