Overall, very good grinders and I enjoy using them. Big fan of the overall form factor and the design is primarily what made me select these. Didn't take too long to get used to using them and they perform well. We cook every night and they hold a charge for weeks. Adjustability of the grinders is good as well to accommodate varying types of salt, pepper, etc. That said, so far we have come across a few annoyances and design flaws. The first is the fact that in a little under 2 months we have visible cracks in the upper body of the grinders for no reason at all. I wonder if perhaps it has to do with swelling of the batteries but regardless not acceptable. It doesn't seem to impact operation though so for now it is what it is. The next item is the fact that the buttons are incredibly sensitive. We find that we accidentally trigger them when picking them up to move them. The third item is that there seems to be an inconsistency in the power of the motors between the two grinders we have. Even with the spice reservoirs removed to take spice consistency out of the equation and with both fully charged, one of the grinders seems noticeably more powerful. Will be curious to see what this means over time for the longevity of the grinders. All in all, it made me realize how much I enjoy electric grinders but I'm not sure if these will be in my house all that much longer given the problems that seem to be presented.The cover for the grinder is difficult to pry off so we are just leaving it off. But you have to be careful not to push the on button when picking it up.This pepper grinder is GREAT!! I love it!!Works well. Would buy again.TIP: to unclog, hold upside down and turn on for a few seconds!Love this product! No batteries and holds a charge a long time. Works great!These grinders work but after about a month and a half both of them has developed cracks in the cylinders.You have to click it again to stop it. The ones where you hold it are so much more convenientThese cracks have been appearing on these grinders. I don’t remember anything more then maybe knocking them over on the counter. Definitely no drops from heights greater then 1 foot.Everything else has been great. Great for grilling since you can use one hand to start and stop the grind.
