On Shark Tank, the hit reality show where startups pitch their products to celebrity investors, a disclaimer says, "No offer is being made to or solicited from the viewing audience."

But viewers are more than happy to bite, even when the Sharks don't. Some products have sold out immediately, and a few of the show's castoffs have been scooped up by other investors.

Check out these most successful products from "Shark Tank." See if they hooked the Sharks — or got away.

Hooked the Sharks? No.

Maybe it was the terrible imitation of Kevin "Mr. Wonderful" O'Leary at the door during the product pitch that turned the judges off. Either way, the Sharks really missed out on this one!

Since the show, DoorBot has a new name and newfound success. It seems like every other house has a Ring video doorbell now, and Amazon has agreed to buy the company.

Ring allows you to see and speak to the person ringing your doorbell in real time, via an app. There are several models, starting at $159.95.

2. Chef Big Shake's shrimp burgers

Hooked the Sharks? No.

After his daughter declared she wasn't going to eat meat because of animal cruelty, "Chef Big Shake" — also known as Shawn Davis — made burgers for her out of shrimp.

The Shark Tank investors passed, because they were stymied by the chef's ask of $200,000. But now his company makes millions.

The shrimp burgers were sold in grocery stores and now are offered in restaurants and on Amazon. And, Chef Big Shake wants to start a restaurant franchise.

3. Scrub Daddy sponges

Hooked the Sharks? Yes.

The smiley-face Scrub Daddy sponge is a little product that fixed a big problem. It gets hard in cold water and softens in hot water, allowing it to wash away grime on both sides of cumbersome utensils.

It's also odor resistant and easy to clean.

Shark Tank's Lori Greiner invested in the innovative sponge, and the Scrub Daddy has made $50 million since getting exposure on the show. You can buy the sponges as singles or in packs.

4. Squatty Potty

Hooked the Sharks? Yes.

If taking care of your bathroom business gives you trouble, a company called Squatty Potty has developed an ergonomic stool that promises an easy and pain-free No. 2. It claims to align the legs and back in the perfect posture.

Two Sharks — Kevin O'Leary and Lori Greiner — went in on this product together, and they were immediately rewarded. In one day after Squatty Potty appeared on the show, the company made $1 million.

The basic Squatty Potty sells for about $25.

5. Ten Thirty One Productions

Mark Cuban wasn't too frightened to invest in Ten Thirty One Productions.

Hooked the Sharks? Yes.

Ten Thirty One Productions has brought haunted house attractions into the 21st century. The innovative company's high-tech, ultra-realistic frightfests are not for young children or the faint of heart.

The creepy characters that accompanied the pitcher in "the Tank "were downright terrifying!

Mark Cuban wasn't spooked and invested $2 million for $20% of the company, which has been growing steadily.

6. Lollacup

Hooked the Sharks? Yes.

Lollacup is a sippy cup that has a straw, handles — and a lot of character. The design and bird shape makes it easier for toddlers to get every drop.

The product also is free of carcinogens typically found in plastics that can leach into beverages. The couple behind the cup got the idea after seeing their toddler struggle with more awkward sippy cups.

Two of the Sharks made a $100,000 deal for 40% of the business. If your kid would love a Lollacup, you can buy one for $15.95.

7. Coffee Meets Bagel

Coffee Meets Bagel is a dating-and-discounts app.

Hooked the Sharks? No.

Coffee Meets Bagel is a revolutionary dating app. Rather than matching users with random people, it uses Facebook connections to match people who are already in similar social circles.

Would-be daters see only those other users who have expressed interest in them. When date plans are made, the app sends coupons for local restaurants.

The owners of the app rejected Mark Cuban's stunning $30 million buyout offer because they wanted to retain majority ownership.

8. BuggyBeds

BuggyBeds don't let the bed bugs bite!

Hooked the Sharks? Yes.

BuggyBeds are like "roach motels," but for bed bugs. They're glue traps (in a "BB" shape) that can be placed under a car seat, couch cushion or mattress.

The company that created them says BuggyBeds are a proactive solution to a pesky problem. You can trap bed bugs even before you know you have them, and stop the infestation from becoming so large you get bitten.

A pack of four BuggyBeds sells for under $5. Sharks Barbara Cochran and Daymond John invested a combined $250,000 for 25% of the company.

9. Wicked Good Cupcakes

Hooked the Sharks? Yes.

Not every city can have a great cupcake bakery, so Wicked Good Cupcakes' idea of shipping gourmet cupcakes in adorable jars all over the country quickly took off. The company made $8 million in the year after it appeared on Shark Tank.

In an unconventional twist, the show's Kevin O'Leary invested $75,000 in exchange for a cut of every cupcake sold. What a sweet deal!

10. Copa di Vino

Hooked the Sharks? No.

Think of wine and you might think of Napa vineyards or a sommelier offering samples at a fine restaurant. Maybe that's why revolutionary Copa di Vino never made the Sharks bite, despite being featured on the show twice.

The product is wine sold at retail in a plastic cup, with the kind of seal you'd usually find on a cup of applesauce. Of course, the cup and the seal are made to seem, uh, elegant.

The cups of wine can be found everywhere now, including at supermarkets, drug stores and gas station convenience stores.

11. Proof Eyewear

Hooked the Sharks? No.

Proof Eyewear is a line of fashionable glasses for hipsters with frames made of wood. In addition to looking really, really cool, the frames are made from sustainable sources and are more environmentally friendly than traditionally plastic frames.

Two of the Sharks were interested in the Proof pitch, but the brothers who own the business said no thanks, because they felt the Sharks really didn't believe in the product.

The eyeglasses are now sold at hundreds of stores, and on Amazon.

12. cellhelmet

Hooked the Sharks? No.

The durable cellhelmet smartphone screen protectors are made of either liquid glass or durable glass and come with lifetime warranties.

During the Shark Tank pitch, the inventors tried to drill a hole in a phone encased in cellhelmet, and it was unscathed.

The Sharks weren't interested because they thought bigger companies would have the same idea. Other investors jumped in, and the cellhelmet company is thriving.

13. The Lip Bar

Hooked the Sharks? No.

The Lip Bar produces handmade, natural lipsticks in wild colors that other companies wouldn't touch, such as "Night Owl" (black). The brand also has a portable lipstick bar used for promotions.

The Sharks said no to The Lip Bar, with Kevin O'Leary telling the company's founders that the competition would crush them like "colorful cockroaches."

But the Lip Bar's vegan, cruelty-free products are now sold at Target and have been featured in Cosmopolitan and Ebony.

14. The Rocketbook

Hooked the Sharks? No.

The Rocketbook calls itself a smart notebook. After you write on the pages, you scan them using an app and the camera on your phone. Then, you can save your work in the cloud or some other online storage option, or you can send it to someone else.

Once the book is filled, you put it in the microwave to erase all of the pages and start over. That's right: It's a notebook that goes in the microwave.

The Sharks couldn't catch on to the idea and passed. But the company seems to be doing more than OK — it says it has had more than $10 million in sales. Rocketbook prices start at $27.

15. Eco Nuts

Soap nuts, the primary ingredient in Eco Nuts

Hooked the Sharks? No.

Eco Nuts is a line of products made from soap nuts, which are really berries that make a natural soap. As with Tide Pods, you're not supposed to eat them!

On Shark Tank, everything seemed to be going fine until the Eco Nuts founders mentioned that they got sick handling the nuts. The Sharks also were put off by the $1 million valuation of the company and by the assertion — quickly retracted — that Eco Nuts was "No. 1 in "the market."

A couple of the Sharks made offers, but Eco Nuts said no. Today, the products are sold nationwide, including on Amazon.
