Customer Reviews


Service: Super product reasonably priced & delivered promptly

Product: As described & arrived promptly

Service: fairly quick and all items included

Product: stands out and effective.

Service: Thought it was fine until I got an email saying 'Ms Jamie Mardle' when I'm male.Our response: Hi Jamie, thank you for bringing this to our attention. May we apologise for the clerical error and assure you that this has now been corrected. 

Product: Fast delivery. Fine, no dramas.

Service: The fastest service ! ordered late afternoon, turned up with the postman by 10am. Well Done Seton 10 out of 10

Product: Excellent

Service: I placed a single order which arrived along with your unasked-for catalogue. I was then telephoned by someone from Seton asking how I felt about everything, then an email came, then today an envelope with another copy of your catalogue and now this feedback thing. I don't want to hurt anyone's feelings but, honestly, all I wanted was a couple of signs which I ordered from your web site without needing or wanting a paper catalogue. I did not seek this persistent searching for praise. It is self-defeating and ultimately irritating . The signs were good. There.Our response: Thank you for your feedback. We are pleased to hear you were happy with both the products and service. We have amended your account so as to prevent further catalogues and promotional emails being sent out, as per your indicated preference. Here at Seton we do pride ourselves on the high standard of products and service we provide, and are always looking for new ways to improve, and to exceed the expectations of our customers. The feedback is optional, but very much appreciated. Kind regards, The Seton team.

Product: Good
