Product Overview
Adjust your soil with Mag-I-Cal®! Jonathan Green Mag-I-Cal® for Lawns in Acidic Soil helps rapidly raise soil pH that's too low and stimulates healthy microbes in the soil. Healthy, lush lawns thrive in soils with slightly acidic to neutral pH levels ranging from 6.2 to 7.0. When soil pH levels drop between 4.0 to 6.0, this creates an environment for weeds to thrive and grows a lawn full of light green unsightly grass.
Mag-I-Cal® for Lawns in Acidic Soil contains pelletized calcium carbonate, or lime, in a completely soluble form that is immediately available to rapidly and efficiently raise soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. Where it may take several bags of lime to balance low soil pH, Mag-I-Cal® for Lawns in Acidic has the power to do it all in just one easy application!
Additionally, Mag-I-Cal® for Lawns in Acidic contains humates to stimulate beneficial microbes in the soil.

Reliable, affordable, and user-friendly
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
The installation process was straightforward and didn’t take much time at all—even if you’re not particularly handy, it’s easy to figure out.
What really stands out is how flexible the arm is. It adjusts smoothly in multiple directions, making it simple to position my monitor exactly where I want it. Whether I’m working, watching something, or multitasking, the range of motion makes a noticeable difference in comfort and productivity.
It’s also very sturdy once set up. My monitor feels secure, and I haven’t experienced any sagging or instability. As a second screen mount, it integrates perfectly with my desk setup and helps keep everything organized and clutter-free.

Solid Build, Easy Setup
Size: 17"-49", Style: Single Arm
I picked up two of these mounts — one for my 34" curved LG ultrawide and one for my 30" MSI ultrawide — and both have performed exactly as advertised.
Build Quality & Value
For the price, this thing is built surprisingly well. It feels solid, looks clean on the desk, and doesn't have that cheap, flimsy feel you'd expect at this price point. Genuinely impressed.
Assembly & Installation
Setup was straightforward. Everything you need comes in the box. The only tool you'll need to grab yourself is a ½" wrench — have that ready before you start and you'll be done in minutes.
Mounting Options
Two ways to mount it: clamp-on or through-hole (use an existing grommet hole or drill a new one). Both options feel secure once locked down.
Sturdiness & Adjustability
Once mounted, the arm holds firm. No drooping, no wobble. Repositioning the monitor is smooth and easy — tilt, swivel, height adjustments all work well even with the larger ultrawide panels.
One Thing to Watch
The tiny limiting screws ship loosely packed inside the arms. They're small and easy to lose if you're not paying attention when you open the box. Dump the contents carefully over a flat surface before digging in.
Bottom Line
If you're on the fence about a monitor mount, stop overthinking it and grab this one. It handles large ultrawides without breaking a sweat, installs fast, and won't break the bank. Highly recommended.

Initial thoughts
Size: 13"-34", Style: Single Arm
Getting everything set up took a bit of time and patience. The adjustment system wasn’t the most intuitive at first, and I ran into some confusion while trying to dial in the right positioning. However, after working with it for a while, I was able to get it pretty close to exactly how I wanted it.
One thing to note is that making very fine adjustments can be a bit tricky. The mount is also slightly wobbly, and it’s fairly easy to bump the monitor out of position if you’re not careful. It’s not a dealbreaker, but it’s something to be aware of if you prefer a perfectly stable setup.
That said, the overall construction feels solid and well-made, and once it’s in place, it does its job effectively. For the price and functionality, it’s a reliable option that gets the job done—even if it takes a little effort to get there.

Holds Backpack Straps Together
Size: 6inches-60PCS
Good quantity for its price. It’s a good quality and durable. I use it to hold my Loungefly backpack straps that I hang on my wall and it does its job perfectly. It’s reusable too.

Perfect for small normal cables lying around.
Size: 6inches-200PCS
Cable ties to organize my random cable is what I needed in my life. The quality is solid and it's easy to use and adjust. They hold well without slipping and the size is perfect for use with normal cables. its about 6 inches long so its gives you a little less than 3inch radius considering they way it is suppose to loop. I think realistically, its more like 2 inch radius. It is versatile and can be reused considering its velcro.
