The new aquarium hobbyist has many challenges, but none is more annoying than the chore of adding water, every day, to make up for that lost to evaporation (a.k.a. topping off/up).

This is an inexpensive quality knife set!
Size: 18-Piece, Style: Traditional Handle Design, Size: 18-Piece, Style: Traditional Handle Design
I have been a Chef for 17 yrs. and from experience know you don't get quality in an inexpensive knife set. This AmazonBasics Premium set really impressed me. The knives I use and have at home are mixed matched because I like good hefty knives. My wife always rags on me that the knives look crappy, so I got on here and started reading reviews. I was not gonna spend alot of money on a set knowing that I have good knives already. Then I saw this set, and looked at the video.
I got them in TWO days, and when I opened the package I was expecting the block to be split, chipped, or have saw marks. As you can see the one I got was flawless. I then took out the chefs knife and smiled. Easily comparable to a 8" Zwilling JA Henckels Pro Traditional Chefs Knife. It has the same quality, heft, and balance. TRUST ME I KNOW!!!! Beautiful knife. The thickness of the blade is equal to my Victorinox Fibrox Chefs Knife and I paid $45. for that knife alone!!! This here is a quality product at a good price. Treat them with respect and they will last for YEARS. If your looking for a good complete set, a nice wedding gift, of just looking to replace the "crappy" set you have look no further.

Amazing for the price
Size: 9-Piece, Style: Traditional Handle Design
At a higher price they would have been 4 or 3 stars, but for $50 this is an insane deal. The steel is pretty good quality. It almost seems like it's hardened VG-10 but I think they would advertise that if it were so I'm guessing it's a cheaper stainless steel that just comes harder without being treated though I'm just speculating based on price. Anyways they're flat ground, take an edge easily, and hold it reasonably well. Nicer knives would certainly hold an edge longer but I'm pretty happy with them. The flat ground shape of the blade is actually ever so slightly convex as well, it's not too apparent in use but you can certainly see it in the reflection. The serration on the bread knife is the inverse of what I would prefer, rounded metal with points cut into it vs points extending from the blade with the rounded parts cut out. When the rounded parts are cut out it's easy to sharpen. When the points are cut out it's almost impossible to sharpen.
The handles are the downfall of the knives. They're not smoothly finished and while they look alright they feel like a cheaply cut (although very solid) piece of plastic which is exactly what they are. A little bit better finishing on the handles would really improve the knives.
The holding block serves it's purpose well. The sharpener is ok but below average, though the rough steel rod sharpeners just aren't great to begin with. Diamond coated rods are much better, though ceramic rod sharpeners are the best.
Overall I love the knives and I'm glad I bought them. For the price they're the best deal I've ever found, no question. I love that there is no logo on them, but I just don't like to see branding in general even if it's a premium brand. If you're buying this for the bread knife or the sharpener, don't, they're not good. If you want the look and feel of a $300+ knife set, don't buy this, you'll be disappointed. If you want a good quality knife set but aren't willing to spend $300+ then absolutely buy these, they're great.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.
