Can't use the email contact site. Tried 4 times and get error message . I bought a PCC661 cordless circular saw and used it 3 times and the drive gear broke. Now the part is discontinued and I can't get a gear . Online complaint after complaint with pictures of the same gear failure in many many other saws of this model . They knew the gear design or metal they used was flawed but still sold the saw. You can get every part except the gear (the part that fails on most of this model saw ) It's horrible that after 3 short uses I can get a part to fix the saw and their online contact site also is a failure as I tried 4 times to use it . User's recommendation: Don't buy their cheap junk . They sell you a product they knew had a part that failed over and over but still sold it. Crooks selling junk . Save your money .
