Too much thread locker comes on the screws.

Love the mount but deducted one star because the screws came mopped in Yellow thread locker making it a royal pain in the a** to lock down.  Just an FYI, you will not be able to use a fatwrench or the old method of feel and the short end of the allen wrench to know that the rings are properly torqued and not crushing your scope.  Mine also came with some cosmetic blems on the rings where the screw threads in which is kind of a downer when your paying this amount of money for a mount.  All other areas of the mount however are machined and finished well.

Screws come loose on seat and button gets stuck.

Knobs themselves are ok, but a lot of variation with the back where it is threaded. Some flush, some recessed and not well machined threads. Speaking of threads, NONE of the screws was long enough for a standard 3/4" thick cabinet door. The 1" screws measured only 7/8" to 15/15" and these knobs need at least 1 1/4" to engage the threads - which are recessed. You'd think with so many comments, the Seller would fix this by discussing with the distributor. No. Had to make a 20 minute round trip haul to Home Depot. Good price on the knobs though.

its ok but screws cross threaded in my monitor and then phillips pattern stripped, and monitor is too wide for the base to keep it level on my desk.

the screw and where you put the nut was in bad state, i think that They put a lot of pressure to tighten the screw.

I like the finished  product. The only problem I had was these crazy locks for the screws.  They are not user friendly and don't go on without a lot of difficulty. Some went on easy, others were ridiculous. The finished product is nice though.

The numbers are great, very nicely made. However, the screws are not good. I hung 4 numbers, so I had 8 screws to drive; of those, 4 snapped in half as I was screwing them in. They break right where the threads meet the shank. VERY frustrating when you have drilled precise holes for correct spacing and you have to move your number over to avoid the broken-off screws. Also, it's a bit odd that they are using square-headed screws when virtually all screws these days have gone to Phillips... very easy to slip out of square headed screws and damage your nice new numbers. I had to go to the hardware store, buy full-threaded shank screws (the half threaded shank is a bad idea in this case, very possibly why they broke off), and then figure out a way to color the heads properly to match my numbers.

Investment in your hardware. might need to re-tighten the screws over time.

I found some wear and collapse on the threads. It's difficult to make it fit at the initial inserting becaus of the collapsed threads.

Out of 40 (4 packs of 10) ordered, 1 came without screws.

To get through our cabinets, I had to get longer screws. The ones they come with are 1" long. I needed 1.5". Most cabinets have 3/4" doors, so 1" screws are fine.

The finish is closer to chrome than to satin nickel. But every brand seems to have its own flavor of a satin nickel. In other words, we have a satin nickel plumbing fixtures, appliances, etc but they are all a little different, but these handles are certainly the shiny-est of the everything we've installed.

Now for the main reason for the 2 stars: these pulls are actually 3 pieces. the feet or attachment points are separate pieces that are screwed into the main bar. During shipping several of then (3 or 4) came loose, and I don't trust them to stay screwed together. They may or may not loosed over the years. However when you need to remove them, to paint or refinish your cabinet doors, I'll bet that a lot of them come loose at that time - which isn't the end of the world. I've put some lock-tight on all the screw threads of the feet that attach to the bars.

The screw threading is a little rough, but I haven't had any cross-threading issues - yet.

I previously bought this shelf and then recently bought another one. While I definitely like the appearance of the shelf, I hate the fact that the screws come inside the tubular portion of the brackets. It is very difficult to get the screws out, which is what another reviewer had mentioned. I had to shake the bracket to get some out. And in other cases, I have to stick a Phillips head screwdriver inside and unscrew enough that the the screws were not interlocked. The screws should be packaged separately in a plastic bag.

The shelf is good looking but the screws are packed inside the rods that hold the shelf.  They are IMPOSSIBLE to get out so I will have to get some new screws and leave the screws that came with the shelf inside it forever.  VERY poor planning.

Out of the box the bolt had bad threads, had to buy a replacement bolt from hardware store before I could install.

Would have been nice if the screw wasn't filled in.

Mounting screws are too short for my cabinets, don't see a reason why, since there's plenty of thread and space beyond the thread.

The saw the screw lock works, the pins fall about 6 times per turn. And you have to turn it many times to take the lock off. If you are picking the lock, you have to pick it about 30 times to take it off. Thats great!

It feels like a strong enough lock. I REALLY wish there is less space between the lock and pin shaft. Tons of room for a pry bar to test the threads on the screw lock. Thats why im deducting one star. Fill the space with metal washers (preferably stainless steel) to avoid that problem. I threw in a rubber grommet for noise reduction.
