Here are a few customer reviews, I will be adding more soon as I receive them, they have not been edited in any way except for the names being removed to protect my customers' identity.

"so i got the cube, reacts VERY well to silicone spray, and it makes very nice turns and corner cuts =]
THANKS TUCKER!"

"I am absolutely thrilled with my order.  I ordered it on Saturday afternoon, and the package arrived by Monday morning.  I wasn't expecting it until later in the week, and I have never before gotten a package so quickly.  Thanks Masterthecube.com!  This is the best purchase I've ever made!

-P.W."

"Just received the caps that you sent. Thanks again for the replying so promptly and resolving the problem so quickly. Your cubes are a god send!! Without them I probably would've started to develop carpal tunnel syndrome. They are great after lubrication! No popping or any flaws. Thanks for the great product! I've already started referring you to all my friends.

"Hi there

I got the cube in good time, only 7 days from postage (considering I’m in South Africa), It’s of great quality and I’m very happy with it.

Thanks a lot.

"First off this was definitely the best online ordering experiences I've had. I got the cube exactly when Tucker said I would and the cube itself is great. My previous Rubik's cube was also Rubik's brand but un-lubricated. The difference between the cube is much better then I would have expected. I cant wait for the DIY cubes to come out so I can order one from here!

Thank again! Scott"

"Well...I just got Tucker's awesome cube, and I'm comparing it to my old petroleum cube...his is way better. First of all, NO black gunk at all, I hated the gunk...ewww. Second it is slightly faster, but the speed is noticeable.
Third of all...petroleum sucks. And contrary to popular belief, petroleum isn't something you should never use, but silicone is just better."

Another review...

"Let me first start off by saying "wow!"  Now let me try to explain my thoughts in somewhat of an order..
 
I knew from the first email how serious you were about taking care of your customers.  For this, I praise you.  Your response time to emails is the fastest I've ever experienced!  That means a lot to a customer such as myself.  You were happy to answer all of my questions and concerns and were nice enough to upgrade my shipping at no cost.  And talk about fast!  I really appreciate how fast you shipped the cube and how quickly it arrived here only a few days of my purchase.
 
The cube is just as I hoped it would be.  Perfect condition and much easier to handle than a standard out-of-the-box cube from the toy store.  I havent played around with it all that much since I just received it, but from my initial experience, I know it will keep me happy.
 
Overall, I'm really glad I chose to do business with you, Tucker.  You have a great business going and your customer service cant be beat!  I appreciate everything and when its time for another cube, I'm not thinking twice about where I'm getting it from!

 
Thanks again,
 A Happy customer"
