3 nef nef bottles were purchased about 5 months ago.
The first 10 days were fine.
Then, the aluminum cap started releasing a black color on both the bottle and the cap, making it impossible to close the cap on the bottle. It needs to be cleaned every 3 to 4 days.
I called the store where I ordered them and their communication was impeccable.
I asked them not to replace the bottles but to send me plastic caps so that I wouldn't have the same problem again.
Eventually, I sent back the bottles as requested by nef nef and they sent me back 3 new ones, one of which was broken.
Within 15 days, I had 2 more bottles with the exact same problem.
Frustrated, I called nef nef this time and not the store that treated me perfectly.
I told them the whole story and asked if they could assist me with 2 new plastic caps, and the answer was a flat-out no...
No interest whatsoever...
Well done nef nef...
The bottles were thrown away after 5 months...
