GORDON COOPER | Director, SES (Entertainment Services) Ltd

I have been purchasing power connectors from Phase 3 for some time now. Their product is top quality, the sales people I have dealt with so far have been very friendly and helpful, their pricing is competitive and their delivery has been exceptional considering I’m ordering from Alberta, Canada.
All-in-all, I’d give P3 Connectors 5 stars out of 5.
