I've been using Brother products for over 30 years.  
One thing you can do to make them last longer is to cut the corners at a 45 deg. angle then cut the two corners caused by that cut to 22 deg. or use a curved nail cutter.  
This gets rid of the square corners of the label which have a tendency to peel if you wipe across it to clean the panel or whatever it is attached to.  
Thirty years of experience and I am still pleased with the work.  I've built more instruments for R&D than I can count and that is how I labeled them as NASA usually didn't have funding to send them out for silk screening (well unless it was for the shuttle.  They always had money).
