Good shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space.
It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅
Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost.
Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!

Very sturdy but heavy
Size: 42 inch 2 Tier, Size: 42 inch 2 Tier
Easy to put together. A little bit too heavy for Sheetrock. I had to use some bigger screws.
I love the look with my cabinet.

Incredible job very thorough
Format: Paperback
It's been 20 years since I took my FP-C exam at the Air Medical transport conference in Reno 2003. I was fortunate enough to take Lori Montanez's 12 hour review prior and to have the study guide she published. I still have that guide and it was great. You all who put this together did an incredible job in every way . It could no be better. The text the pictures everything perfect. I'm proud of you for doing such a great and professional job. Everyone should have a copy of this book either for exam prep and for regular review following their completion. Thank you.
