Loved the restrain and breathing groups. The other two just didn't work/make sense - eardrums really doesn't fit with the connection, and the quarts group doesn't hang together at all.

Spinoffs! Really? They are sort of, but not quite, homophones - and of a uncommon subject. Did anyone get that group? Also, charger isn't quite right - there's an 'in' missing. The other two groups are good.

@igor the spinoffs group made no sense:one homophone, one misspelling with a k instead of a c, which made it s different word which doesn't sound similar, one completely different word which doesn't quite rhyme, and one not quite homophone- too inconsistently connected to the link to make a group. In the 'charger' group, eardrums really didn't work for me - I thought the other three just about worked, but eardrums was just wrong,:

Two nice lines, but not a great wall. I agree with Igor & Malcontent.

I've read the answers, but I just don't get how two of these groups are groups.

Definitely not a successful grid.

Very good TY!

This started off really well, with good lines, but the other two spoilt it for me. On the bright side, I don't feel annoyed with myself for not seeing those two links, even when the groups were sorted out for me.
