Not comparable in uk
Product does not work in uk it’s a lot of money to pay goods not comparable in uk bit of a rip off

Works great(uses AM channels)
Works great, would recommend getting a extendable antenna with it. Uses AM channels so mainly for long range use. Check what type of channels your local group uses if you have one but is great overall

Can only copy Indian people
Purchased for UK use. No matter what channel, or UK location, I can only copy people who speak in Hindi? Which is, चॉकलेट फायरगार्ड जितना उपयोग।.

kind of has a short range but does pick up close trucks definitely worth having

Absolutely love this thing. It reaches 8 miles, at least. Bought it because my company owned, factory installed, company maintained one doesn't work properly and I need a cb working in the mines and this hand held is perfect.

I had a Cobra before but it had a lot of issues. When I got this one I put it in my car and plugged it in and it's working great. Although it doesn't hold the channel when I turn it off and turn it on It's a pretty good radio.

The radio has a BNC connector, so the supplied short "rubber duck" antenna can easily be replaced by a longer antenna that extends the line-of-sight range. Since you are probably buying this to use from a vehicle, you will be disappointed with the range if you try to use the stock antenna inside a vehicle. You should also buy an antenna that you can mount outside the vehicle. Longer/taller will be better. Note that most external antennas have a cable with a "UHF" connector for a non-handheld CB radio. That can be used, but you will also need a BNC to UHF adapter (not very expensive). This radio is advertised as "4 Watts." The FCC limit for conventional amplitude modulation (what this and most CBs do) is a 4 Watt carrier. When 100% modulated, that gives a 6 Watt total power level. (For single-side-band [SSB], which this radio, and most CB radios do NOT do, the FCC limit is 12 Watts). I bought a cheap power/SWR meter ( https://www.amazon.ca/dp/B086QPTXQT?psc=1&ref=ppx_yo2ov_dt_b_product_details ) and verified that it was within the 10% power accuracy spec by comparing it to an oscilloscope when driving a 50 Ohm terminator (yes, I'm a nerd). If I use 9 Ni-MH batteries, the carrier power (no voice into the microphone), is only a bit more than 2 Watts. The spec sheet says 4 Watts at 13.8 Volts. But the supply voltage at 1.2 volts times 9 Ni-MH cells is only 10.8 Volts. If you use 9 alkaline batteries at 1.5 Volts per cell, that's 13.5 Volts. A car battery is about 12.6 Volts, and when the engine is running, the alternator will run at around 14 Volts to charge the car battery. The radio has an external-power jack, and comes with a cigarette-lighter plug. It will use the cigarette-lighter power instead of internal battery power when plugged in, and re-charge Ni-MH batteries (if the switch in the battery compartment is set properly). I have a 15 Volt power supply that fits the cigarette-lighter plug. Using that power supply, the carrier goes up to about 4 Watts into a 50 Ohm load, vs about 2 Watts on Ni-MH batteries. So I conclude that the power is pretty close to as-advertised, and at the FCC limit, if you use alkaline batteries, or the cigarette-lighter plug, but lower with Ni-MH baterries. You will probably be happier for use in a vehicle if you use the cigarette-lighter plug to get a bit more power, and use the tallest external antenna compatible with conditions.
