Really like them!
I have tried out different kinds of bamboo toothbrushes and it was hard to find ones with medium strength bristles. The other ones I tried had such flimy bristles that they wore out in a few weeks.  I ordered this pack of five three months ago and am still using the first one in the pack.  The toothbrush is very durable and I am very pleased to have finally found the right kind for me.  Would definitely order again.
