I decided not to wait to get the correct tips, as they wont be here until Tuesday next week, and went ahead and tried the Iron with the "standard chisel tip" which was much too large for what I tested the iron on.
In short, the iron worked exactly as advertised. It heated up within the 10 seconds that they claimed it would and instantly melted the 60/40 resin core 0.32 gauge solder I was using making the job very quick and clean.
The iron has a rotating button on the front of it. In the down position the button is "Locked" meaning you cannot depress it. Depressing the button is what "turns on the iron and a very bright light to boot". In the UP position, the button can be depressed, thereby turning the iron (and light) on. When the light comes on, you know the iron is also on. What I found to be a little awkward is having to keep the "button depressed" while holding the iron to do your join. I pretty much had to hold the iron like a pen and try to manouvre it, along with what was being soldered, to make the join. This is something that I hope will become more natural the more it is used.
The iron is very light though so very little effort (if any) is required to use it.
Although I have only tried one soldering job with it, I am impressed by it in terms of it's light weight, the speed at which it heats up (unsure how quick it cools down though) and the effectiveness of the temperature and resulting job it does. ISO-TIP claims 125 solders per battery charge. How accurate that is is to be seen and whether or not heating times and iron temp are effected by a reduced battery charge are also to be seen.
This IS a very nice little compact soldering iron and ideal for those awkward or small soldering jobs. Would I give up my corded Hakko System to solely use the ISO-TIP Iron for all jobs? No I wouldn't, at least not at the moment until time has proven it's reliability. Would I recommend having one for those small soldering jobs such as wires to SMD's and resistors or for decoder wiring or for soldering in tough to get to places? Most certainly I would, without hesitation.
I should also add that ISO-TIP has numerous types of Tips for this Iron and it does come with "2" standard tips from the beginning, one of those being the chisel tip I used for the test. They also have 3 variations of the same tip, although I am not quite sure what the exact difference between them.
So, if you have a spare $70 (in round figures) laying around and want or need a very good, handy cordless Soldering Iron, I don't think you could go too far wrong with this ISO-TIP "60" Pro Charge Iron.
PS: If I felt the iron was "poo" I would have said that as well
