Query: Poor Quality

I have used Gardenia products for years without a problem until my purchase of a Gardenia Flower Shower Nozzle. The cap keeps coming off with the slightest water pressure and it leaks.I bought three nozzles at the same time and I have the same problem with each. The plastic threads are not adequate. Poor engineering or poor quality, but I expect Gardenia has written all the reviews you see on this site.
