DO NOT BUY - NOT USER FRIENDLY
Color: White
This mop has the worst design and cheaply made. I do not recommend buying it. Cons: the cord is too short; there is no place on the mop to wind up the cord when you put it away. The cord just flops all over the floor. HOW CHEAP IS IT NOT TO PUT HOOKS ON IT SO THE CORD CAN BE WOUND UP? The mop does not stand on its own. It goes straight to the floor no matter what position you put it in it will not hold an upright position. It lays in the floor. The water compartment does not come off the mop. You have to pick the whole mop up and hold it under the faucet to fill. Or lay it on the floor and get a glass of water to fill. Makes a mess. One more big gripe - THERE ARE NO SETTINGS OTHER THAN ON /OFF AND THOSE BUTTONS ARE WERID. There is no high, med, OR low setting. Lastly the mop pad in the photos was not the one it came with. It had one very thin like disposable one. PROS- NONE. I RETURNED IT .

5 month review- still a favorite!
Color: White, Color: White
I purchased this steam mop 5 months ago and it is still one of my favorite purchases. I have used it every week 1-2 times per week and it still works great! My house has wood flooring throughout, two cats and a lot of traction. I can finally relax knowing my floors are clean and sanitized! It heats up very quickly and the cord is long enough to do large sections of floor at a time. I highly recommend this purchase! Especially if you have pets or kids.

I spent the $20 I saved on stuff to make this thing functional-ish
Color: White
The only reason this is getting three stars is because I do like the ability to shut off the steam and also it puts out the perfect amount of water and cleans well. For the bad, the design is terrible in four important ways as mentioned in other reviews (which I wish I had read before purchase so my fault). 1. This thing will not stand in its own unless in a very particular position and even then a slight gust of wind sends it toppling. 2. The one hook cord storage has to be the stupidest design I have ever seen. I did buy a command hook so I could wind the cord so that takes care of that issue (other than no notch to secure the plug to the cord). 3. The cord is not long enough but again I remedied this with a 6ft extension cord though I’m sure this is probably not recommended somewhere in the instructions so I take my own risk. 4. I did not like the pad included but have a ton from my old Shark steam mop (RIP) and they work well enough with this mop so it’s not completely useless. I would not recommend this mop to anyone. It is a bit cheaper than the Shark mop I was looking to replace but wish I wouldn’t have let my cheap side win and it’s spent the extra $20 to get a mop I know I like.

Quality Knives At A Bargain Price
Size: Steel King 15Pcs 10.4"×7"×15.4"
I have had these knives for almost 18 months now and they have held up great Edge retention is fantastic, and as long as you treat them right and don't leave dried tomato sauce on them for 5 days, no rust to speak of or even any discoloring! The build is fantastic and they are well balanced. I still can't believe I got this set for the price I did. I have a collection of pocket knives, I own Japanese wet stones to sharpen and understand what 8cr13mov, s30V and 14c28n is in knife production. (It's metal alloys BTW.) Having said that, I was a bit picky in finding a knife set that was quality built, had good steel and didn't cost $800. I honestly don't know how they are producing this set and not losing their shirts. Full tang design (One piece of steel from tip through the handle to the butt), and has nice glass fiber reinforced polymer handle material. I can't find any reference to this set in particular for what steel is used, but based on using various steel through the years I have a pretty good idea what this probably is. (BTW, I hate to break to you. At this price, it's absolutely NOT German steel...and that's okay anyway.) Brodark references Japanese VG10 steel with their other stand alone chef knives. It is common in the Chinese knife industry to copy an alloy alloy and call it by it's original name. It's NOT Japanese steel. What is commonly referred to as VG10 is 10cr15mov or 8cr15mov. Both are fine steel to use for a "general purpose" knife and perform similar to Japanese VG10, or even US made 440c stainless...perhaps even a little better than 440c. The steel in these knives is pretty dang hard, which makes me think it is 10cr15mov. The 10 is the Chromium content in the alloy. More chromium, more hard, more hard ='s more brittle. There is a balance of how hard without being brittle. Some knife makers use super hard steel to get a wicked sharp edge that holds for a while...buuuut then after a year of use you see all the chips along the edge or perhaps even a tip has snapped off. That's hard, brittle steel. You can't fix chips unless you grind them down and create a totally new edge on the knife and start over. These Brodark knives find a nice balance of hardness for edge retention but enough give to not chip or break off under general use. Like I said, almost 1.5 years of use and no chips, bends, or scratches. I still can't believe I paid around $50 for them. Incredible.
