Excellent product and customer service I have bought the 800 watt blender in November 2019. I really liked the immersion blender and whisk and they are used almost everyday. They take up less kitchen space and have enough power to do the job efficiently. After almost two years of use the whisk attachment accidentally stuck into sink and broken. Now here comes the biggest advantage of this particular product over thousand similar products: After Sales Service! They have their own website and own customer service. I could easily contact via online chat and they have assured me to send a replacement whisk base attachment. Now a days you can hardly find such service with product costing less than 50$. I am really happy with the customer service.

This is the first bullet type blender… This is the first bullet type blender I've had so I don't have anything other than my larger Ninja blender to compare it to. I'll say having used it immediately after getting it and it was very surprising. In a fraction of the time I was able to make a smoothie with hidden veggies for my autistic daughter and she loved it. She is extremely particular about the consistency and hates any chunks in her smoothies. What a huge success! Clean up was super easy. I basically just rinsed the cups out after and they were good to go. Would definitely recommend it to others!

Excellent HEPA!!! I have purchased 7 or 8 of these Air Filters because they are exceptional units! They are small, quiet, powerful and take in air from three different directions. I highly recommend this product! I'm more than satisfied after using them 6 months already!

Quick Responses, Kind Attitude The little rubber or plastic part inside the main blender attachment broke, and I emailed for info about a new one. The person that helped me was extremely quick to respond and sent the info over to the people that handle replacement parts immediately. I really appreciated the kindness and professional attitude from Christine from KOIOS!

The people at koiosshop.com were disingenuous. I was led to believe that in return fo providing a review of your Immersion Blender I would receive an Amazon gift card. I provided the review and the required documents, but it appears you have reneged on your part. It's too bad. While I like your Immersion Blender, I will not buy any more of your products, nor recommend other's do so. Steve Warnick
