Love My New Blender!

I love my new blender, product as described. My only complaint is the condition of the box, it looked as though it had been opened at some point. Maybe a open box item or a return. I had planned on keeping the box for storage but it was so damaged upon delivery, every corner taped, that I couldn't get it back in the box. Literally, the box fell apart. It looked pretty rough but fortunately the mixer itself was intact and unbroken. Also, it was shipped in the original box, not wrapped. See photos.

I received my Dyson quickly within 3 days

I received my Dyson quickly within 3 days, it was very well packaged. Thank you.

Hampton Bay Truitt Vanity Light

I spent a lot of time looking for a vanity light for my new bathroom. When I finally found what I liked, it was out of stock with no option to order. As I continued to search for another vendor, I finally found Klimdi. Luckily for me they had the exact item at a lower cost.
Shopping their site was easy. I was notified of shipping and delivery dates quickly and the package arrived with no breakage.
I was very pleased with every aspect of this transaction.
