My dental hygenist reccomended the oral b they had been using for 11 years, got the same model and I'm very pleased.

Mine have adjustable elastic straps. When they stretch, takes 5 seconds to make them tighter. Don't know brands off of the top my head, but the design is definitely present in many models online. They get so little wear, not sure I'd ever need to replace. Stitching has remained 100% for about a year and a half.
