How does it work?
Logiblocs is the electronic discovery system that helps you understand the world of technology around you as you create your own inventions. Everything in today's world runs by the same principles that logiblocs demonstrate. Inside each logibloc is a printed circuit board and every block is colour-coded for the function it performs. By plugging together logiblocks in different combinations you can create circuits and virtually write your own simple program to build each new invention.
Logiblocs are colour-coded by function:
YELLOW BLOCKS - are the input which triggers the system by createing a signal from a variety of sensors.
BLUE BLOCKS - are the connection which sends the signals from place to place.
ORANGE BLOCKS - are the logic which 'ensures everything happens in the right place at the right time.
RED BLOCKS - are the output which communicates to the outside world through light and sound or by turning things on and off.

Pretty Nice
Color: E-Blackpro 4, Color: E-Blackpro 4
I’m not sure why the promotional photos show these hooks with the bent ends pointing down. To me that makes no sense, as it seems they are using them upside down.
It makes more sense to me to have the bent ends point up, so the items being stored do not slide off. Additionally, the shorter bent hooks make no sent to have on the top, as they would limit how far back you could place a shovel or other tool.
When using the hooks with the bent ends pointing up, you can place your lighter bulkier items on the long hooks, but then use the short hooks for those heavier items (if they fit), as that gets them closer to the magnets and will have less leverage to make the magnetic hooks fall free from the metal they are trying to be attracted to.
In my example photos, you can see how the shorter hooks do not obstruct the shovels and other tools from being stored properly and the bent ends then also help to prevent the tools from sliding off the hook.
Overall, I am very happy with the hooks. I’ve had a fondness for magnets since I was a kid, so I have a very realistic expectation of the limits of magnets and these magnetic hooks perform as well as I would expect.

Strong magnetic hook with only one small con
Color: E-Blackpro 4
I got the four-pack of magnetic hooks and the magnets are indeed strong. You have to reasonable with how much weight you hang off of these though!
The longer hooks help with holding multiple items.
I've used them for shovels and rakes and they hold up just fine.
The only slight con is that I wish the ends of the hooks curled up instead of down to keep items from sliding off as safety precaution. You can just turn the hook upside down but then the shorter hooks are at the bottom.
They work for what I need them and can hold power tools as well.
The hooks are sturdy and the magnet power is impressive.

Magnets are strong
Color: E-Blackpro 4
Arrived fast. Magnets are really strong on my husbands metal peg board in the garage outside. The only draw back, the rings are slightly long for a work bench area. Wish they were 3-4''.

High Quality and Operability - Great!
Great mouse! Not only good, but feels and operates as well as, or better than a Microsoft mouse, and a lot more reasonable! Comes with AAA batteries, the USB transceiver is stored inside the battery compartment (good when packing and traveling), and a white support strap lays down below the installed batteries so that it is easier to remove them when its time to change the battery. Be sure to go into Control Panel/Mouse and make any click-speed or mouse movement adjustments to your liking. I plan on buying another one of these for my second HP laptop. The USB transceiver is immediately responsive and you will see a red laser at the bottom of the mouse.
