Took 3 grown men to mount but it’s been such an awesome addition to our kitchen. My wife’s coffee knook is excellent now

Color me impressed.
Size: 41 Inch Extra Long, Color: Rustic Brown, Size: 41 Inch Extra Long, Color: Rustic Brown
My husband and I were looking for a shelf to replace the one over our coffee station. We just needed more room for travel mugs and other assorted coffee items. Most of our kitchen is done in the wood and black metal tones so when we spotted this, we were excited. We placed it in the amazon cart and purchased. Shipping took a little while but it was packaged well and nothing was damaged. It came with everything needed to build and hang the shelf including the dry wall anchors. My husband was able to put it together fairly quickly but hanging it was a two person job. The shelf isn't SUPER heavy... but someone needs to hold it while the other person levels it and mark where to mount the anchors. Once it was up, it was sturdy and looks great! We're very happy with this product. It is perfect for what we wanted to do :)

Looks decent but is slightly under engineered
Size: 41 Inch Extra Long, Color: White Faux Marble, Size: 41 Inch Extra Long, Color: White Faux Marble
Five stars for packaging, quality of materials and instructions. It's a really good looking product out of the box. No scratches or defects in workmanship. Material fit and finish is very good. If you've ever assembled anything from Ikea, the hardware will seem familiar. The problems that led to me giving it 3 stars occur in the engineering. All of the weight transfer to the center with just four corner anchor points creates a sag. If you drop a 4' level across the top after installing, it's a noticeable 1/8" dip in the middle as gravity pulls on the unsupported center. If you're one of those people that notices an out of level picture on a wall from fifty paces, this is going to be a problem for you. Being that I knew it would only get worse with time and eventually make me insane, I installed a very small L bracket in the middle under the bottom shelf, pushing the entire thing up until the deflection was gone. I also tossed the anchors that came with it as those are for concrete/block walls and used metal EZ anchors that are rated for drywall. If you use the included anchors in 1/2“ drywall, there's a good chance they'll pull out. Toggle bolts would also be a good alternative. Another small detail that's missing is the lack of a plug or cover for the four exposed cams making up the vertical center support. Depending on your viewing angle and how much stuff you'll store will determine if these are visible or not. Including a simple white decal would have been reasonable. I used some white, stick-on melamine screw covers I had lying around to try and hide the cam locks better. Lastly, I wish this were made in plain white. While the faux marble somewhat matches our dining table, The veining is too pronounced. Plain white would have been better.

Revelation for the serious Bible student
Format: Hardcover
The most complete discussion of Revelation I have read. Be aware it is written in a very academic style, so not for casual reading.
