I came to this online store from Googling replacement rubber feet for industrial strength floor fans. While the selection of available rubber feet had an adequate amount of variety, unfortunately the specific style/form I needed wasn't among them. Nevertheless, I settled on the most practical looking feet, and after installing them, I am completely satisfied.
I have to admit that I have only been using these feet for around a few months with only a light to moderate usage. While they have worked for me thus far, I cannot comment on how the feet have lasted over time and/or heavy usage.
The only suggestions that I have to the retailer are that, (a) provide better quality pictures of your products, and provide more pictures - yours are blurry and some have ambuguous/not enough info, and (b) I'd be happy to send detailed information & pictures about the existing rubber fan feet that I was looking to replace so that your company may be able to either find a manufacturer or manfacture them yourelves and then carry them via your online store.
