I always need fuses but the right one is never available. This range includes several fuses in common sizes from 5A to 30A. PLUS there is a bonus. The fuse puller also has sliding contacts and a light that attaches to the fuse terminals and lets you know if the fuse is good. If it lights up, the fuse is good. By the way, do not use it with the fuse installed. So a good selection of quality assurances (Buss has been in business for decades) as well as an extraction tool that can also test fuses. . HIGHLY RECOMMENDED!
