Is this grammatically correct? - 1

"Good luck on carrying your lenses every six month to the Nikon service."

Yes it i s grammatically correct, but it does sound weird though.

That's correct, but it's strangely worded…

*months

Um YOLO

It's technically not wrong, but it would sound and flow better like this:

"Good luck carrying your lenses to Nikon Service every 6 months."

BTW I use only Nikon lenses and have never once had to have them repaired, not even after dropping them onto the floor from a table.
