Good and cheap
This filter holder can be described as a bargain and an insider tip. In terms of quality, I can't tell any difference to the much more expensive alternatives from other manufacturers. The adapter, also made of metal, is included and can be easily inserted into the filter holder. The filter holder is locked using a screw that can be tightened enough to prevent accidental twisting. This is solved differently with other products, I like the K&F solution a little better.
