I used to shop at Cubezz for many years and have bought over 40 cubes from them. I recently ordered a cube which arrived with a missing sticker, which had gotten caught on plastic wrapper and "bent" beyond use.
If nothing does wrong, they seem OK. I don't care about their limited English because I can understand them and my Chinese language is far worse!
My feeling about Cubezz went bad when Customer service insulted me by saying "PVC stickers don't tear, just put it back on and send pictures". I spoke with the another customer service rep who made excuses for the first rude customer service person. The second rep said they would get replacement stickers or I could ship it back registered mail "Not express" and they would pay return shipping and replace or refund."
I asked "How does this work? Do you email a shipping label?" No answer. "Were you able to obtain replacement stickers?" No answer. I went to the post office and they said I must complete a customs form and the cheapest rate is $27.75 to be delivered in 3-4 weeks. Express rate is $35.35.
I again told the customer service rep this and her response was, "Don't complete a customs form and don't use express" At this point I am angry because I'm getting the runaround. They know that the shipping to China is expense, They know you can't get around the customs form!
I have switched to shopping at ZiiCube and they are sending a replacement cube for one with sticker problems. Ziicube's items arrive lightening FAST!
I ordered from Cubezz two weeks before ZiiCube and ZiiCube items arrived first! I ordered a cube from Cubezz in June which still has not arrived. They said they would mail a replacement over one month ago which still has not come!
Aliexpress and is even better faster and cheaper or not much more than Cubezz. Aliexpress gave me a quick rapid refund when one cube never arrived. Ali has an excellent and fair customer resolution process. ZiiCube and Aliexpress have great prices, even with shipping - just look around.
I used to think the free shipping at Cubezz was great but they must use the worst carriers! Items take much longer and stickers get damaged. Also, they do not care if you have trouble. They are not at all flexible or generous. I know many Chinese-Americans in business and graduate universities and I have lived in China. So I know not all Chinese retailers are cheap and rude like them. Just look around.
Also, if you ask how many of an item is in stock, I strongly suspect they lie and say "One" or "The manufacturer won't make anymore" I fell for that two or three times- those items are still in stock!
Cubezz - You have lost a lot of future sales over a $12.99 cube (which costs you a few bucks)
