Hi JOGR,
I am not against your prouduct if it is approved. You state thata it it ABC rated, but I see no proof of that, nor do I see any mention of it in your ads. You also seem to state that you are not concerned about approval, since you are selling it to users who don't require an extinguisher that is rated. To me, that's the same as saying that the life preserver I am selling is fine, trust me, even though it is unrated, since you don't really need an approved life preserver in your case.
If your device is approved by NFPA or UL, where is the approval sticker mounted? I didn't see one in your material. If it itsn't approved, why not? I am not attacking you personally, but if you are selling an unpermitted device, you are placing your customers at risk. Underwriters Labratory does an excellent job of rating all types of devices, and weeding out those that fall short of the safety standards needed. I would think that you would proudly display your UL certification.
