This review is from: Higher Nature Salt Pipe - Relief From Breathing Problems (Personal Care)
This is a nicely designed little ceramic salt pipe, but it is a sealed unit and the salt cannot be changed.
I found on some other websites (the instructions with mine did not mention this) that it is designed for use for 5 years at 15-20 minutes per day. If I had known this before I would not have bothered to buy it.
