Inzer Forever Lever Belt
Strengths

- +Genuine leather, 4" width, 10 mm or 13 mm thickness options

- −13 mm thickness has a long break-in period (4-6 weeks of regular use before it stops feeling like cardboard)
- −Lever buckle limits day-to-day waist-size flexibility — refit takes a screwdriver
- −Inzer's customer service has a reputation for being slow on warranty claims; ship-time is also longer than Amazon-native brands
