## Customer Reviews

### ⭐⭐⭐⭐⭐ perfect replacement for existing window cranks
*by K***. on March 12, 2025*

Our house is twenty five years old and our window cranks are wearing out. These window cranks are the perfect fit. They are not only attractive but they are easy to change out and are quite durable as well. The white color matches our window frame color perfectly. The fold in easily to accommodate the wood blinds on the window. The price is reasonable as well. You will not be dissapointed.

### ⭐ Plastic adapters are absolute trash
*by J***E on May 23, 2022*

If you're lucky, you can get one to five cranks of a window with one of these.I followed all of the instructions to apply this product to three different brands of window, and the plastic inserts shredded to pieces very quickly.The supplier likes to say "the set screw is required for proper operation," but that's NOT what the set screw on most windows is for. The set screw is meant to prevent vertical movement of the handle so that it does not come off of the post it is attached to. It is not to be used for securing the handle during rotational movement. The interlocking "teeth" on the post and the handle are supposed to be doing that.As the "teeth" on this product are thin strips of trash-bag quality plastic, they don't do the job.I suppose, if you had brand new, very light, very-well greased windows, these could last six months to a year, but in a real window, in a real house, in the real world, these are just useless toys.

### ⭐⭐⭐⭐ Does the job!
*by D***Z on September 29, 2024*

Good, does the job. But the plastic inserts eventually will strip in a short time. Especially if used frequently!
