The airbail bail arms used by Daiwa are often more to replace than the reel itself cost. And I can't think of a suitable repair that would last.
I am not aware of the Consumer Rights Act in France but a lot of shops offer and stand by their guarantees. Decathalon sell Daiwa reels. I got three last year and even the cheapest has a 2 year guarantee, and as long as you keep the box and receipt and it hasn't been obviously abused they will honour it.
My advice would be to look out for the offers at Lidl and get one of their Crivit reels at €13. Three year guarantee and as good as my cheaper Shimano and Daiwa reels.
Yes. In the Lincoln area there are shops called Boyes who sell acceptable reels like these which probably come from a similar source.
A mate who fishes most days swears by them. His philosophy is that it doesnt matter what reel you buy, even the expensive ones, it will be bail arm that goes first, so a cheaper disposable one will do.
I must say a decent reel feels better but his ideas have some merit.
I broke the tip section of a Daiwa match rod. Daiwa wanted about £70 for a top section of a £90 rod!!
