hark Tank has been running successfully for 12 seasons and every season we are introduced to a lot of great entrepreneurs and their products. It's exciting to watch the best products walk away with good deals from these Sharks.

Not all products shown are great, some get a deal and some don't.

The products that are rejected in Shark Tank either fail altogether or makes it big outside even without a deal from the Sharks.

Ring DoorBell is the biggest deal turned down by the Sharks.

The Sharks regret it even today.

Ring Doorbell is a mix between a doorbell and an apartment buzzer.  
The Ring lets homeowners see and speak with whoever is at their door.

As the founder of the Ring Doorbell said in his pitch to the Sharks, "think of it as caller id for your front door."

The device is triggered by motion and can be linked to Alexa.

The Ring was introduced on Shark Tank as 'Doorbot'.

The founder of The Ring 'Jamie Siminoff', asked for a massive $700,000 for a 10% stake in the business. The Sharks were not interested and all of them thought it was too soon and that the product was not particularly different from other available solutions out there.

Well, time has proven that they were all wrong. The Ring has become a super hit with the customers and it continues to grow its business with newer versions of the product today.

Now in 2021, we have a much advanced version of The Ring:

From the ratings of this new product and the reviews of the previous versions of The Ring Doorbell, it's clear that this is popular among the customers.

The Sharks missed out on seeing the future success of The Ring when this was pitched to them.

Shoes and Sandals are things humanity has mastered since civilization.
But then something new comes along that tries to make footwear better and durable.

Xero Shoes are a science-based version of man's favorite footwear since shoes ever came into existence.

Xero Shoes are the only footwear that has been shown in independent university studies to be bio-mechanical, identical to the barefoot with a layer of protection and padding.

Xero Shoes comes equipped with a patented 'Feel True' Sole.

The product description says that these soles let your foot bend and flex naturally and protect your foot while giving your brain the feedback and stimulation it needs.

Xero Shoes has earned very nice reviews and strong ratings on Amazon.

Many customers are in awe of the comfort this footwear provides.

During the pitch, the founders of Xero Shoes asked for $400,000 for an 8% stake in the business.

The Sharks said that the valuation at that point was too high. Kevin even countered with $400,000 thousand for a 50% offer, but that was immediately declined by them.

Well, right now, Xero Shoes has established well on Amazon and those founders must be running all the time to their banks to encash massive cheques, whilst wearing these comfortable shoes.

In season 6 of Shark Tank, Melissa Butler came to Shark Tank with a line of vegan liquid matte lipstick.

The Lip Bar comes in many different shades. One of the product's highlights was that they were vegan and cruelty-free.

The Lip Bar was named so to encompass the essence of a bar. Their lipsticks are named after well-known cocktails available at a bar and also the lipstick has different colors based on color of the cocktail it was named after.

The lipsticks are made from shea butter, avocado oil, jojoba oil, and other organic ingredients.

Melissa Butler asked $125,000 for a 20% stake in their business.

None of the sharks seemed particularly enthusiastic at the idea of a new line of vegan lipsticks.

Robert mentioned that he did not like the logo. Mark Cuban criticized the branding, Lori and Damon said the makeup industry would have no space for this product.

The LipBar proved all of them wrong. It has beaten all of their estimations and has proved quite successful on Amazon.
