After experimenting with many forms of identification, including but not limited to: tattoos, toe punches, zip ties and rubber bands, Sharpies, fingernail polish (don't ask), and every leg band on the market, I started using zip wing bands in 2012 and, as a means of permanently identifying a bird from hatch to death, nothing I've found even comes close. I put them on right out of the incubator and, if correctly applied, they almost never come off - I can count the ones I've lost on the fingers of one hand.
There are some drawbacks, visibility being the main one. They are hard to read on a fully feathered bird, so on birds that I retain as breeders I add aluminum butt-end leg bands once the bird is finished growing (preferably with the last 2 digits from the wing band #) for quick ID. But as long as you leave the wing bands on and only use leg bands as a secondary form of ID, bandettes are the easiest to read on a moving target, if you don't mind replacing them often.
Some other drawbacks with the wing bands:
You have to be pretty precise with placement, not fun with day old bantams. The band goes through the wing web, between the bone and the tendon. If you are too close to the edge and miss the tendon the band will pull through that thin piece of skin and come off, but if the bone ends up inside the band you'll have to cut the band off and start over. And, of course, you have to be careful not to hit the bone or tendon when you poke the band through. (Not as complicated as it sounds, National Band has instructions and a video tutorial:

You also have to have the tabs aligned exactly when you crimp it or the band won't seal, which is kind of a pain since the soft aluminum bends when you push it through the skin and you have to bend it back.
For the same reason, it's difficult to apply these bands to older chicks. By the time they leave the brooder the skin is tough enough it's hard to get the band through, it just bends.
Hope this helps! I think you'll be happy with them.
