I've had a VX6R for many years, having purchased one not long after they were released. It has withstood the test of time and endurance all of these years and I continue to use it everyday. It faithfully works just like new and appears "kind of new" as I give it a good scrubbing every few months as it is waterproof to some extent (can't recall if it's IP66 or 67?).
After all this time my two original batteries still work fine. I have also purchased two other batteries about four years ago from eBay,(not OEM batteries) and they are beginning to fail/not hold a charge. An option (and by default) on the VX6R is it displays the battery voltage when you switch it on. A full charge will show about 8.2 volts and I'll usually swap out the battery when it's down to 7.4 volts or so (it'll still work fine, it's just my routine). My use of the radio is mostly receive for several hours, with maybe a combined TX time of 30 minutes a day. With this usage I change the battery after two or three days.
The thing I like the most about the VX6R is its durability. It's super rugged and has shown it's toughness on a number of falls to the ground over the years (e.g. while hiking). I mostly it a lot on 220 and as you must know it has low power only on that band, but it works fine for me working a repeater about 20 miles from my place.
The comment about needing to have a reference card in the field to make changes is spot on. I can only recall the few frequently used functions to use in the field as the keyboard use to configure the radio seems a bit complex.
I was surprised to see the KGQ10H sells for $220, not much less than the Yaesu. But here's the thing, I recently bought a Radtel RT470X (tri-band TX/RX with more RX bands) as a backup radio. It has a better quality build and function than I expected for $33 from Amazon.
So in summary, after my long winded comment, I'd suggest the Radtel instead of the KGQ10H and save yourself the cash. But if you want a super durable HT that'll last forever and has better specs, buy the VX6R.
Good luck!
