You will probably be quite happy with them, but don't get sucked into believing you are going to transmit and receive 36 miles with these units. Here is the fine print from Midland.
Maximum range can only be achieved over water or open rural areas under optimum conditions.
I have a pair of Motorola GMRS/FSR radios (basically the same radio) and they work great up to about a mile. They make great little camp radios. Two miles is really iffy with any terrain.
You might consider buying them locally at REI for example. The price is going to be about the same but you can take them back and exchange them much easier if you decide they don't work for you.
Now if you really want 36 miles, lets get you interested in Ham Radio.
That has been my experience too with several different types of GMRS/FSR radios......functional range of about 1 mile. I have Motorola radios now and they are extremely handy to have around, especially with kids. I keep 4 radios in the SMB all the time and just use disposable AA batteries. The rechargeables never worked as promised and lost their charge pretty quickly.
I have a set of the Midland Hunting radios & they work awsome. I have gotten anywhere from 1/2 to 7 mile range, depending on conditions. I use them all the time in the malls- lots of steel there too, but not as much as a ship, they work great for us.
Current vehicle: 08' Power Wagon
Future vehicle,hopefully: SMB 4x4 RB 50, Purpose built for off-roading & camping, in style of course !!!
I have midland's very similar to that and one of the batteries has never held a charge. Good thing mine can run on AA batteries- just make sure the rechargeable pack can be replaced with standard batteries.
Otherwise they've been good. Can't use half the channels because I'm not paying for an FCC license for everybody, but it hasn't been a problem.
