Ok first off I have a Nixon 51-30 and a Nixon player that I needed to resize. All in all I was eventually able to do it but let me tell you what's wrong with this retarded piece of cheap, cheap plastic.

FIrst of all when you put the watch band in the empty space and then you twist the knob on the right with the small screw end, it is supposed to poke into the actual hole of the watch as you screw in. It works ok, BUT ONLY if you are DEAD ON. Problem with this is, if you put it in the empty space, YOU CANT EVEN SEE IT FROM THE TOP OR THE SIDES. You basically are trying to screw into the hole to pop out the pin, but are unable to see it. I scratched the side of my watch attempting this multiple times for each hole until I got it right.

That was just for my smaller watch. My Nixon 51-30 is admittedly a very large watch. However the band itself wouldn't even fit into the band slot. I had to completely remove the screw part of this and do it all myself manually. I grabbed a hammer and smacked the end of it (which is extremely flimsy and loose by the way) It took so many tries the actual metal for this thing was bending because it kept flopping around everywhere. I was again finally able to pop out the pins and back in but only with a sacrifice. IN the many, MANY attempts it took, I scratched the shizz out of my watch and regret it. Go find a real toolkit, I would give this thing zero stars because it will definitely damage your watch in the process!!! DO NOT TRY!! I WARN YOU!!
