We used Cookson to install commercial openers in our shop and do some repairs to other doors. Once giving the go ahead it took quite awhile for them to finally come out and do the job. The sales rep, Michael Consalvi quoted the entire job incorrectly causing much confusion and hassles for the poor install crew. However, in their defense they installed the correct, and more expensive opener for the agreed price. The install and service guys are great and friendly.
Here's why I dropped the stars so low: I called them to come out and do a powered gate install at the same location. Not only did Michael not show up to quote it at all, but when I called back to speak with Jim (who was very friendly and helpful), despite being assured to the contrary, NOBODY CALLED ME OR CAME OUT. Seriously, the economy isn't that good here in AZ. Don't blow off a paying commercial customer. I'm not some "tire-kicker". I'm the manager of a shop who needs an expensive gate.
