I'm from Fullerton and I came over to Superco looking for an induction cooker for my aging Mom. Ken bent over backyards to help me out with this purchase. He is highly knowledgeable and I appreciate his expertise. He did not try to sell me anything. I highly recommend Superco for all your appliance needs. Simon

Great service, friendly customer support and a wide variety of furniture and electronics for your home. I bought AC splits from here.

Superco has been our family for 40 years. Ken Cheng is Best sales manager. Professional and Personal services is off the chart. We will Continue To visit a store for our family ‘s future needs.😊

I went in to look for a new blender for the summer and for my kids to use. Was greeted quite nicely when we walked in and the cashiers were very friendly. Purchased a Cuckoo hand blender for my daughter and she loves it. Easy to use and wash. 5 Stars.

Growing up in the Diamond Bar area, SUPERCO has always been there for us whenever we need an appliance! This is where my Taiwanese parents buys rice cookers, water heaters, couches, pots and pans—what have you. Now we’re the ones shopping here, who would’ve known? We only come in once in a while because their appliances are quality (and rarely needs replacing), but it’s great that SUPERCO is such a cornerstone of the community. Thank you for always being here!

Julie (the boss) was a pleasure to work with as we were looking for appliances and even a potential kitchen remodeling project. Highly recommend Superco! There is a reason they've been in business for so long.

This store is the true definition of a mom & pop shop where you can feel comfortable asking questions for your needs. They do carry good quality Asian brand appliances that has been in business for generations.

Jacqueline, Ken and Christine were so wonderful to work with buying a new washer unit!! They were so welcoming and helpful. I would recommend their services buying any appliance you need! Thank you kindly you guys! Keep up the good work!

I’ve been coming here for years and years now and I’ve always had help from Ken! He would be the first person to greet you when you arrive. I’d always ask him where everything is and he knows what to recommend and knows everything about anything I ask. This time I came in looking for a new refrigerator for our new house. He was able to direct me to where it was, while also suggesting which one I should get. Great customer service as always, and that’s thanks to Ken !

We have been long term customers and their service has been trustworthy. This summer we bought two big items from Superco. Ken (sales manager) is very patient and responsible. He made sure the delivery service went well and kept good communication with us when we had questions. We also appreciate owner - Judy and IT - Max. Great team work overall and we can always come back.

Good place for family appliance need, Cantonese sales representatives Ken, very friendly in assisting products needs, definitely would recommend to everyone.

Look no further for lower price. Here's the best deals you can find in town or online. Fabulous and honest customers service. Sue helps us pick out the right washing machine at a reasonable price.

Sales man - Ken Cheng is super nice and friendly he helped my mom and I to pick and choice the right message chair and give us great price! Would recommend superco to all of my friends and family !

Very good store, extremely friendly staff. I felt able to look around slowly without being pressured to buy. Good prices on everything, and especially beautiful furniture.

Jacqueline helped with our Quick and easy pick up for cal king bed!

Ken Cheng was nice enough to let me test out their new massage chair and did not pressure at all. I definitely took a short nap and left feeling so relaxed. He let me know they have a legit finance program for installments. Thank you for the massage and nice customer service!
