I purchased some electrical products such as switches, cables, wire from the imperial world trade as a production manager. when I call them for some changes in my order, They were very responsive both via phone and email. Shipping was fast and also packing is great so our order will be arriving safely. After 2-3 days the order was at my doorstep. Then after I have doubt about order and I sent an email to them about doubt. In just an hour they reply me with very professionally to explain my issue. I am very impressed and be a regular customer of IWT.
