Due to the very good reviews I bought three of the hot shoe covers - two for my Fuji cameras and as a reserve. Unfortunately, they do not fit as good as I thought it would be, they sit m. E. not tight enough. It is not so that they fall out at once, but if they are not fully inserted or are 2mm slip out (which may indeed in the camera bag happen to anyone), they quickly lose their grip.
By comparison, a while ago I got a cover with integrated spirit level as a giveaway ... which is made of a softer plastic and sits much firmer.
Conclusion: if I had before can try out, I would have probably not purchased ... but maybe they sit also only Fujifilm cameras loose. Therefore, instead of 3 just 2 stars.
