I have looked at three separate lots of Geeetech Mega R3 boards, sold between February 2015 and June 2015, and all of them are defective.  The support for I2C is non-functional.  Geeetech continues to sell this board, knowing that it is defective, in hopes that customers will not notice until it is too late to return the board.
The defect was first mentioned on their own customer forum back in February 2015, and Geeetech admitted the problem, yet continue to sell the board.
They have promised me repeatedly that each batch of boards has corrected the problem, but they are still selling the same old defective boards.
I have purchased many other brands of Chinese Arduino-compatible Mega R3 boards and they have all worked perfectly.  Only Geeetech boards have had problems, and they have persisted for many months, and Geeetech will absolutely not offer refunds or, obviously, working replacements -- since they don't have one.
I would strongly urge you to avoid Geeetech products because not only are they defective, but the company has been a nightmare to deal with.  They say everything that I want to hear, but deliver nothing.

I started out really liking this product, but just like the cords this product has let me down.  One of the charging ports does not work and the blue LED light is out. I have tried using different cords with it to no avail.  This is now the THIRD defective product I have received, and all of them were from the same order!!!  I will not be buying from this company again.

Very disappointed.  This product is defective with chips on the side, made by the manufacturer and not from shipping or dropping it while packaging.  The chips are consistently in the same exact place and the same exact size.  I not only received this defective once, but when I contacted them to send me a replacement I received it again with the same defect.  In short, I ultimately received this same product defective 7 times.  I was told they pulled them all off the shelves on number three and carefully inspected all the stocked products, but I received it four more times after that, still with the same defect.  Ultimately, I am very disappointed.  Do not waste your money, or more importantly, your time!  This was all from the black colored version, I cannot speak for the other listed color options.

Received a defective screen protector from seller. Amazon had the Seller refund my account. The product would have been nice if it was not defective on the adhesive side. What was really frustrating with the seller is that they accused me of installation error. It was clearly a manufacturing defect when you look at the pictures I provided in this review. There is no dust or finger prints under the defective corners. I personally would not waste your time on this product if your buying for the note tablet. Yes, the gave me a refund. However, the seller cannot own up to the possibility of a defective unit and would rather point their fingers at the customer. There is a wide variety of choices for more reasonably priced tempered glass protectors on amazon; THAT DO THE SAME THING. Case army was OVER PRICED AND UNDERWHELMING.

The bottles are defective and Meguiar's knows and does not care.  I got mine with the Quik Detailer bottle split at the bottom, had leaked everywhere, the towel, mitt and pad soaked.  The products work great, but I am only giving 4 stars because these bottles are a recurring problem.  If the manufacturer fixes the spray bottles and replace them with a bottle that is not cheap plastic, then it would get a 5 star review

I ordered this item from Amazon and received a defective item 4 times!!! The first time, it was the handle which gets scolding hot. I called the manufacture and they told me to return the product to to the seller immediately because it is defective, so I did and Amazon sent me a replacement. But the lid was loose and didn't close snug, never mind the leak proof. So I sent it back  AGAIN and Amazon gave me a refund. A month later, I placed another order hoping this time they'll send me a non-defective item. BUT Amazon sent me back the first one I returned -- with a defective handle. So I returned it for a replacement. Then they sent me the second defective one I returned -- with the loose lid. I tried to order a replacement but Amazon gave me refund instead saying they will review the problems. In my opinion, if Amazon has defective items in stock, they should set those aside and NOT send them to anther customer hoping they won't notice. I hope no one has to go through this ordeal. Until Amazon gets non-defective items in stock, I urge you to wait before you place your order.

I had purchased this product twice and both times was sent a defected product. The first time I received product the light and sound feature did not work. I returned product but turned around and reordered product thinking the first time was a fluke. When recieving the second item was disappointed to see product had the same issues so I again had to return the product. My mother ,who suffers from dementia, would enjoy going to vegas to play the slot machines but her disease prevents her from that activity. Though she would not remember ,after each time, playing this little slot machine I will always remember the disappointment of not able to try and help her experience some joy she had from her past.

This product never worked. They've tried to attribute it to user error yet admitted they didn't even send the proper instruction manual. I've tried everything they suggested but refuse to say anything is wrong with the product.  I've already had to replace this item with a different system since it was a Christmas present yet I'm still struggling to get a return authorization from this company for it. I would not recommend this product at all.

Defective product=A waste of time

This product did not work as when I plugged it into the power outlet, the power did not turn on. I called the company and instead of helping me trouble shoot, they immediately knew it was defective and told me to return it. What a waste of time.

This doorbell is great when it works. All the marketing is about how easy and simple it is to install, which again, it is, except when the product is defective. My husband and I bought a Ring doorbell (as well as a stick up cam) and went through all the installation smoothly. Once the doorbell was on the house, everything worked except the Motion alerts. Which renders the doorbell pretty useless, because not everyone might actually ring the doorbell. After going through MULTIPLE rounds of customer service with nice people who didn't seem to know much aside from the set up manual, they finally said "ok we will send you a new one." It arrived, and eventually it worked.

A few months later, we went to install the Stick Up Cam in our backyard. Again, all the set up and installation went smoothly until it was up there and AGAIN, no motion alerts. We re-installed multiple times, again with nothing. Because we bought both products at the same time we wonder if we got a bad batch. Either way, we expect when we buy a product that it should work the first time. This was especially important for the Stick Up Cam since there is no doorbell to ring, its only purpose is to alert you to motion on your property. Otherwise, there's no point. Now we have to wait for them to send us a new one, and go through the whole process again. This all sounds like a snag until you add up the time we had to spend on the phone to customer service, jumping through hoops before they would send us a new one, plus all the installation and re-installation. Frankly, for a company that boasts simple and easy installation, they might want to make sure their products work.

Completely defective product. I have owned the product for a few months now and one key doesn't work for the lock and now the lock will not even lock.

I would like a full refund. Shame too, because friends have had success with their products.
