Once my son ordered this radio and I saw it I knew I too had to have one or two of these and when I received them I was as pleased as he was. They have been used with great success and meet all of our expectations. Great product easy to use and great price, thanks!

5.0 out of 5 stars Great product with good range and battery life that saved me in an emergency
Reviewed in the United States on June 27, 2021
I actually have both a 155 and 275, but I'd recommend anyone go ahead and get the 275. I really don't see what the purpose of the 155 is except to save a few bucks. It's not that much smaller than the 275 and it has a shorter range.

The 275 is great. The battery will last a few days if you're not transmitting and just monitoring Ch 16. Unfortunately mine didn't come with a DC charging cable so I can only charge it on 120 volts AC at home. I think you can get a DC charging cable for it, but even though it's advertised as coming with a DC charging cable, at least mine did not.

The range on the 275 is great. The longest I have transmitted is about 50 miles to the CG station when fishing offshore when I lost power in an emergency--obviously this was only possible because the CG has some high elevation towers, but the transmission strength with the "Boost" transmission function is more than adequate for long distance. For normal, boat-to-boat communications, given the curvature of the earth, the range is more like 5-10 miles or so.

First, I will say that this radio did work fairly well, when it was working. The audio was clear and the range was good. The screen was bright and the battery life was good.

However, there are quite a few design flaws. First is the battery clip. Our clip broke within one month of owning the radio (fixed with a zip tie around the whole radio). Ours wasn't the only one with this problem, as we have met at least one other cruiser with the exact same issue (became a joke around the table that night).

Second, is the "submersible" feature. By submersible, they mean you could drop it in a puddle 2 inches deep and if you immediately pull it back out, it will be fine. However, anything deeper than that and it will not survive. Ours died after a quick dip from the dock. Friends of ours died after just sitting in the dinghy in a rain shower (yes in the water at the bottom of the dinghy about 2 inches deep).

Third, is the terrible belt clip. There is no retaining mechanism

Usually buy ICOM's, but needed one now and this fit the bill. I like that it is floating in case of overboard fall. Screen is very readable even in direct sunlight. Nice loud speaker and easy to grip. High, medium and low power ranges. Only charges in special charging station, but station can also screw to a wall to save desk space. Bought to use in my skiff and am quite happy with it. Waterproof to 3 feet for 1/2 hour if attached to something that sinks it. Price was almost half of my usual brand and it seems to work just as well. Time will tell, but I think I'm going to be quite happy with this one. I like the high wattage capability.
