Friendly and accommodating staff. Great products. They offer discounts to churches (there’s a minimum purchase value). Really does cater to all your audiovisual needs. I’ll surely shop there again.

Quality items at affordable prices with knowledgeable and helpful staff. If what you are looking for is available here it doesn't make sense importing through a freight forwarder.

Mark Buckmire, Google CET Reviews

I've bought from them in the past on a few occasions and it's always been a good experience. I recently made a purchase and happened to have a manufacturer issue. CET immediately replaced the item with the least inconvenience to myself. When buying these types of equipment, it really is best to use a local and reliable supplier and CET is hands down my choice.Plus the staff are always helpful and respectable. Good job folks.
