I manage a Lab and order beakers and flasks frequently.  These are a great buy, decently thick side walls.  everything a good beaker should be.

This wall mount did the trick.  It took a little time to get it all leveled off, but in the end it was a great buy for the money.  And it looks good

I bought this for my college age daughter. I was afraid it was going to be a mistake (because of the other reviewers comments) but the price was right. It turned out to be a terrific buy. It went together easily, supports her books & laptop, can easily be used for her artwork. The drawer is CLOTH. It is not going to hold a bunch of heavy items well. It is pretty large though. She has used it for 5 months now with no complaint.

This looks great in the wall and works as expected.

A well built mount and priced right. I took EXTRA time, centering and measuring before making any holes in the wall. Have a friend help you if you need to hold it up and mark the wall. It's heavy. This helped to complete our renovated living room as we now have a wall mount TV, sound bar, and Xbox Kinect sensor all while not seeing a single wire. Everything is hidden in the wall and into a media closet. I wanted a movable screen just in case we wanted to pivot or turn the TV but we rarely do that. Sticks off the wall a bit so read the minimal depth requirement.

This wallpaper is really nice. It has a texture to it and is a thicker paper that doesn't rip easily like some wall papers. I love the look that it gave my room! Make sure that you get enough paste as this is not self sticking. I purchased 2 rolls and ran out of paste. I needed about 1 1/2 quarts.

Went together fairly easily.  They should space the holes for standard stud spacing. I made life easy and drilled a new set of holes on the top rung. Also, you may not want to tighten all of the hardware until you get it level on the wall. It seemed a bit racked before I hung it up. Then I got it level and mounted, then I tightened the hardware to lock it all down.  Looks pretty good and the price was right.

This was a surprisingly good buy! Looks great in our family room.  The fabric seam is  large so only purchase if you can direct it away from sight.  Installed easily.

These are great for the side wall of my garage.  Being only 12" deep, they don't take up valuable car door opening space.  I ordered three shelf units that were delivered almost next day and in perfect condition.  The first shelf took a good hour and a half to assemble.  The second and third only took about forty minutes each.  I'll be ordering another two today.

A lot of the reviews are a bit harsh for the price paid.  These are not your three minute assembly plastic shelves (all of my plastic shelves sagged and looked ugly after a year by the way).  You will need a screwdriver and some patience.  I did not have to drill any new holes for misaligned screws.  Some twisting was required here and there but it all went together.  The only useful information in the instructions was which part of the shelf was the front and back.  Other than that, just look at the pictures on the box.  A cordless drill with an adjustable clutch was very helpful in snugging up the screws after leveling the shelf.

I don't know about 750 lbs. but these can easily hold several hundred pounds if properly distributed.  The bottom two shelves easily handled three 24-pack Coke/Pepsi cubes each.  I left one shelf off and only used six for more space between.  I plan to add the extra shelves to another section to make a cheap wine storage rack in a utility room.  These can be joined together side by side along a wall if needed.  There were plenty of nuts and bolts left over for something like this.  Be sure to put a screw through the back of one of the shelves or side rails to anchor it to the wall to prevent tipping.

This is a great shelf unit.  I wish it were about 6" wider, but it works as is.  Maybe the company can make another shelf unit the same height yet slightly wider.  The one thing to know is the unit comes with a fastener so it can be bolted to the wall.  While not a crisis, it's being affixed with a zip tie so that makes it less classy looking.  Still, it's a great buy and looks very nice.

I rate this "acceptable plus" but I do not see how it rates 4 or 5 stars.

Shipping and packaging: Product arrived quickly and was in a sturdy thick cardboard package. No damage at all and damage not likely because it is so well packaged.

Materials: It is solid wood with what appears to be a sprayed on stain. The screws provided for assembly are of excellent quality. The provided hex key for the screws did the job but I was a little fearful it might break with heavy pressure. It didn't. The finish gouged a little when I slipped a few times. I expect that the finish will scratch over time and it probably will not be a good surface to put beverage containers on.

Assembly: Good and bad. It's not complicated or difficult but somewhat annoying. The screw holes all lined up properly. It was hard to get the screws started for the top shelf because you have to thread the screws upward into the shelf from below (or the side if you put the thing on its side.) The access to the screws for the top shelf was cramped and there was a limited radius for turning the hex key. The rest of the screws were easier. The instructions were pictures only but they were comprehensible after a brief study. Overall it took me 30-40 minutes. It would go quicker with two people.

Look: It looks ok. It's a simple open design and not unattractive. The finish looks kind of 1950's mahogany. It would be easy to paint of you want to spiff it up.

Utility and Quality: This will work well in the small space I have available by my desk. It's a little wobbly but not terrible. I plan to put my heaviest stuff on the bottom shelf. The fit is ok, though not perfect. By and large the wood pieces were square and straight. Nothing had to be bent or redrilled. Not the most solid thing you will have in your house but acceptable.

Bottom Line: Not bad for the price but not a huge bargain. The materials and manufacturing can't have cost the seller more than $8-10 bucks in Thailand so most of their cost is in shipping and sales. They get a nice margin and you get a serviceable shelf for about $50. I'm not sorry I bought it. They should rethink the design of the top shelf as it makes that part of the assembly a pain.

Love it. It was a little hard to put it together myself, trying to keep the walls upright when screwing everything together, but I managed with the help of a power drill. Unless you're really strong, I'd suggest using one to get everything tight.
Happy with the color and it's quite large in a good way, lots of top space.
The bottom of the bottom drawer you just set in and it's thinner board so don't plan on putting anything heavy on the bottom drawer. The magnet is a little weak, but it's not bad for the price. There was a small nick on the front of the door, but I'm not that picky and with a little dark polish, it would probably disappear. Overall I'm happy.

Nice addition to the decor of a room. Thick and sturdy. Good quality. My only hang up was the wall attachments were not already fixed to the back of the sign. You must apply them yourself. Other than that no problems. This hangs over my bed. Love it!

This is a very great buy. Other than making sure it was very secure to the wall, I love how it accommodates my 70 inch. It moves almost effortlessly. Thanks for such a good product. Well worth the buy.. hands downs
