Duncans

[stefday]

Hi,


I have got 3 Duncans which recently have started to close quite a lot of the time. As far as I can see the parameters have stayed the same.

Does anyone have any idea what the reason for this might be?

Thanks for any advice.

Stef

Is there any sign of tissue recession?

My duncans in particular hate change. If They get moved the slightest bit from their spot, it takes 3-5 days until they fully open again. Have you moved them recently?
