We now have Caframo fans, not cheap, but they push heaps of air, use very little power (0.4Ah), are as quiet as a fan can be, & have a blade design that does not require a protective cage.
We have one which is fixed (757), with adjustment only in one plane, & one on a gimbal adjustable in any direction & with a timer.(Scirocco).
If we’d have bought these when first looking for fans we would have saved wasting all the money we did on lesser fans over the years. If you can afford them you wont be disappointed.

I've got the 743 (around 40$) and it was originally too loud to use while you try and sleep (only time we use them)I had to put a variable speed controller on it to limit it to 3/4 speed also the on/ off button broke as I think its a bit of a poor design and its right on the middle of the fan, great fan but this was my experience with this model.

next time I would look at one with different speeds
