How is the quality of these? i never heard of this brand and can not chance using inferior components on any repairs i do. my reputation's worth more

If you're a professional you should really be using the real ones, i.e. from TE Connectivity (originally Raychem SolderSleeve). I've never used one of these Chinese-sourced ones that was nearly as good as the originals. The plastic on TE's is far superior, the glue spreads better, and the solder melts nice and flows well. Basically, you get what you pay for, and I'd hope a professional would be using the best product, depending on which industry you work.
