No Instructions - Easy to build and study
Size: 4-tier, Style: wall mount&floor mount
I ordered 3, and my wife loves the look of them. They seem to support a decent amount of weight. I supervised my 7 year old (55 lbs) as she scaled a single shelf bracket up the wall after it was mounted, without the planks.
You do need to have some amount of handiness to be looking at buying as it does not come assembled, and does not have the wood planks with it.
A little learning curve I had. Keep the rods only hand snug, not tight, snug, and then as you put it up to the wall adjust as needed to get the heights and widths right to the opposing shelf.
There is also only 8 pipe brackets to hold the shelves down (2 per shelf) and I did not realize this at first and assumed I had 16 (4 per shelf). I had to go back and fix.

Game changing storage!
Size: 4-tier, Style: wall mount&floor mount
I love the shelves. I got to use my own wood which was a reclaimed piece that I found and sanded and then stained. I'm so proud to see them on the shelves. It got so much clutter corralled from around the room and put in one place where it all looks good displayed together. The support pieces are very good quality and I found this to be very good value for the price. I'm very happy with this item.

Good all around, some imperfections on threads difficult to screw together
Size: 4-tier, Style: wall mount&floor mount
I received a complete product as advertised, it's a solid steel design with everything you need to mounted included. One small issue I encountered is that the pieces screw together but they wouldn't screw all the way it felt difficult and possibly if forced the steel might crack. Unfairly enough other pieces did completely screw in. So it's probably because of imperfections on the threads.

Build w/ a Friend, and BYOL (Bring Your Own Level)
Size: 4-tier, Style: wall mount&floor mount
Definitely a two-person job. Not because it's heavy, but a little awkward at first. I installed the first bracket, and my 12 yo assisted. Then, she hung the second bracket, and I assisted. Have a level handy. I didn't want to roll the dice and allow her to hang from the bracket, but it seems super-strong. We hung the brackets 32" apart, and 6" overhang, i.e. 48" x 12" laminate shelves. Gorgeous.

Nice, sturdy kit...would buy again!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Purchasing this kit instead of each piece of pipe and fittings required was a no-brainer. It was especially easy because all pieces are prepainted. It went together with ease.
Mounting was simple with planning, measurements, and a level.
*Note*
I purchase the pine stair treads from Home Depot that are 1" thick and then chemically aged them before adding polycrylic. It is cheaper than plywood and shelving boards, and a full 1" thick rather than 1x12 shelving.
