I have a set of Perfex salt and pepper grinders. I want to know what people out there think of them. I have a chance to buy a larger Perfex pepper grinder but after reading some reviews that after about 6 years the gears are a problem and what can't be done about them, no lifetime warranty most likely also, I wonder if it is worth paying a fortune for one or another salt grinder one even. I want to know what grinders and especially pepper grinders are considered even better than Perfex so I can start deciding when and what I am going to buy one or the other. They have been super but I just need to buy the larger pepper size and think I may be wasting my money since I read some not so hot reviews.
