This is review for 100m product:
1. Frequency stability over voltage change is better than on 800m product, but still no good: about 0.01 MHz per volt on 2-5 volts, and almost not changing on 5-9 volts.
2. Nearly impossible to set specific frequency: 90 degree of rotation of variable capacitor changes frequency all over from 80 to 120 MHz. It is even harder to set flat frequency (for example, 102.6 MHZ, but not 102.6273 or 102.5856).
3. Also metallic screwdriver inflicts on frequency, so when you set frequency by rotation, it will change when you remove screwdriver from capacitor. You need dielectric screwdriver.
4. Size of screwdriver tip needed to fit variable capacitor is VERY small. I hardly found that metal screwdriver tip. Finding dielectric screwdriver that small will be even harder.
5. Low sound volume sernsitivity. You need to speak about 20 cm from microphone to get same volume as average radio station. Sensitivity on high frequency (>5 kHz) is bigger.

All ok

I received the product and tested they said 2v-9v
but I tested with 5v-9v
and the results are 5v don't work properly
9v perform perfectly...
thank you all....

Normally without interference begins to work with 8v-9v, you need to achieve the adjustment so that there are no strong radio stations nearby.

The package arrived in perfect condition and in an anti-static bag, I can't prove it yet but I can barely make extra comments
