If the answer is no, then it's about time that you introduce her to this Lululemon bestseller, which even got Yahoo editor's stamp of approval.

If you have trees in your yard, they probably need a bit of pruning. Compared with a pair of traditional pruning shears, this little battery-operated chain saw makes the job practically effortless. It's only 4 inches long, and there's a safety lock that has to be pressed before the saw activates. Plus, it comes with a handy carrying case, so you can safely store the device when it's not in use. 

"I'm so glad I didn't spend a bunch of money buying a lot bigger electric saw," one reviewer said. "All I really need to do is cut small branches and saplings. This little guy did it with ease. I was really surprised at the power, to be honest with you. ... It cuts through small saplings like a hot knife through butter. I would most definitely recommend this for small jobs."

It comes with an 8-foot hose for hard-to-reach areas, a stair tool, an upholstery tool, a crevice tool and a sample bottle of carpet cleaning solution.

"Amazing results" said one Walmart shopper. "I mistakenly bought a white rug not knowing how quickly it would get dingy and dirty. I also have a dog that tracks dirt inside. This carpet cleaner made all my rugs and carpets look and smell brand new again. The dirty water and debris that it pulled up from my carpets was disgusting, but so satisfying that it's now clean and sanitized."

Summer is grilling season, but if you don't have the space for an outdoor appliance, check out the Ninja Foodi Smart XL Pro. It's marked down to its lowest price ever on Amazon. It has seven different cooking functions: grilling (obviously), air frying, broiling, baking, roasting, dehydrating and griddling. There are also four no-brainer smart protein settings: Just insert the Foodi Smart Thermometer (it’s included) and choose between nine customizable doneness levels, from rare to well done. 

One of Yahoo's shopping writers put this on her summer wishlist, and over 1,300 Amazon shoppers have given it a five-star rating.

"We bought this grill as a way to decrease use of oil and pan frying," explained one Amazon reviewer. "The smart temperature cooking mode is probably my favorite feature. It cooks all kinds of meats, but I've only cooked chicken and steak. The meat comes out perfectly cooked to temperature [and] retains moisture and flavor, with very little mess. The device is also super easy to clean!"

"Bought this a week ago and have used it at least twice a day," added another. "Easy to use and cooks everything to perfection. What have I prepared on my grill? Burgers, steaks, bacon, eggs, baked banana bread, stir-fried vegetables, baked potatoes, air-fried foods, grilled sandwiches and reheated foods. Replaced my toaster oven, air fryer and rarely have used stove (except for steaming or boiling)."
