Bank 1 Sensor 1 on a 1997 Ford F-150 sucks trying to replace. Alex got to my home early and knocked out the job way quicker than I thought. Overall, great experience and very convenient. I'd choose him again.
David was very nice and made my appointment a priority. There was a misunderstanding, however, and he did not have the battery that was requested. A refund is forthcoming, but it is unfortunate that charge could not removed before I was charged.
