The Oregon chains are top notch, however the Amazon web sites on the chains leave a lot to be desired. The write-ups  are all over the place and need to be improved. It is almost impossible to tell from the listings which chain fits your saw. I had to send two back already and while this one will work it is not the model recommended by the mfg. You may find ordering chains from Amazon to be a challenge. The product itself is fine. I could have saved a lot of time by just going to the hardware store.
