Love and amazing for the price!
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Perfect! I'm a renter and didn't want to spend an arm and a leg on something that might not work in the next place so this looked like it would be a good fit. I really wasn't expecting much for the price point but I was VERY pleasantly surprised. It's a great piece. I love assembling things (I'm an Ikea pro) but this had literally the easiest and most explicit instructions I have ever seen. Every piece is clearly labeled. The hardware comes in a bubble pack, again clearly labeled. Rhe instructions are very clear. Another thing I appreciated was the mounting mechanism which is a French cleat. It is much easier to level and screw in a cleat than to recruit help and try to hold a cabinet in place and try screwing it in. I'm a fat middle age woman and I had no problem mounting it by myself. Notice there are no screws visible on the outside. That was a huge selling point for me. Only con is that for the quality of everything else, the shelves are on the thin side, placing anything substantial would definitely make them bow. Background is a scrap of peel-and-stick.

Good cabinet choice
Color: White, Style: Wall Cabinet
I needed a wall cabinet for a recessed area above the toilet. This one fits the area perfectly and provides a good amount of storage in an otherwise wasted space. It looks good as it coordinates well with my white shaker style cabinets elsewhere in the room. It was easy to assemble, doors lined up perfectly, and mounting was a breeze with the included screws and hardware. It doesn't get hard use in this location, but seems sturdy after almost a year.
