Review on 3 Pcs Faucet Aerator Set for Kitchen Sink and Bathroom - Male Thread, Multiple Flow Options, Chrome Finish by Kazuki Vong

My old aerator only shows flow. This model did not fit and I have now learned that most 15/16 aerators have either 22 or 27mm per inch threads. Maybe a plumber could look at that and say the old one was 27 threads per inch. This sits right in the middle at 24mm and could most likely be worked on by pinching with pliers. In order not to damage the threads and thanks to free returns and fast delivery, I ordered another brand. Now I know my threads are 15/16 x 27. Perhaps the aerators should be stamped mm for later use, which is not the case with this one. hence the 4 stars.
