Air today, gone tomorrow.
Used in a commercial setting to deflect air away from an employee's eyes. This was used on a 2' x 2' ceiling air / duct diffuser. The employee is very happy, and the installer is very happy with the ease that the adjustable size and magnets for attachment. My guess is that the deflector will outlast the employee.

Works, can get cracked in shipping if in plastic bag instead of box
Good! This is the only product I found that would fit my type of baseboard register. Ordered two, and one was cracked, but that may have been due to shipment in a plastic bag with no cushioning instead of an Amazon cardboard box. The manufacturer packaging is a regular thin cardboard box, and the plastic is rigid, so any impact would crack it. (Amazon, you should ship this in a cardboard box.) I kept the cracked one anyway bc it still works and is hidden from view behind a sofa. I just wish I could find a duct piece to attach to go under the sofa. They make one for other styles of wall and floor vent but not this one. The pictures are if one under long curtains, not the one behind the sofa. One star off for it being cracked or not being durable, but I would buy it again.

"IT IS FRAGILE" IS AN UNDERSTATEMENT.
Wow. I saw reviews of people saying this arrived broken, or that it broke easily... let me tell you. Mine arrived in perfect condition. I was going to use it to redirect the air from my window air conditioner away from my couch, as it points directly to my favorite seat on the couch and it gets way too cold. The magnets on the side might as well not even be an option because they have 0 strength. The only way the magnets would do anything at all is if you have this laying on the floor, FLAT. I think the magnets were installed just to keep this thing from moving left and right, but that's it. If you plan on mounting this on any other surface thats not flat on the floor, like wall or ceiling vents, you might as well order velcro tape or double sided sticky tape or something because this wont hold its own weight. In its defense, this technically was designed to lay flat on the floor but seriously they couldn't have found a weaker magnet for this... ANYWAY, I used Velcro trape to secure it to my Midea U Shape Window AC. It wasn't holding very well and was wanting to fall off, so I went to remove it to re secure the velcro, and I dropped it... It fell LITERALLY about a 1 foot, onto a CARPET FLOOR, and get this, IT BROKE! I am beyond shocked!!!! No wonder these were arriving broken etc! I will say it worked great for what I was using it for but now will need to re order. Maybe ill just find one of those thin flimsy plastic pieces that can bend and I'll rig something to redirect the air instead. 1st pic is selft explanatory. 2nd pic is how I had it set up. 3rd pic just shows how far the floor is.

It does the job
Lousy quality but it does the job. Magnets are useless.

Perfect air flow
Works perfect for directing the air from the vent from going up to the windows. We have long base board vents so I was looking for something that would be adjustable for there size and also push the air flow out instead of up right to the window and these work perfectly. The only thing is because they are magnetic on the sides and big dog does push it off sometimes. They are pretty durable though.

Been using it for about 6 months now, and it holds up well. Stays in place and directs airflow how I want.

Frost King HD11 Baseboard Air Deflector is for HVAC register/vent that fits up onto the baseboard
Perfect for HVAC register/vent that fits up onto the baseboard at the floor-baseboard juncture. I looked at the details of many vent deflectors that indicated that they were for baseboard registers, but after digging into the reviews found that they were not for baseboard registers. These Frost King HD11 Baseboard Air Deflectors have their magnets oriented so that they attach along the sides of these protruding baseboard registers. That is 90 degrees from the typical deflectors attach on the same plane as the grill where the air comes out. My baseboard registers are around 18 inches wide and extend up the baseboard around 4 and 1/2 inches from the floor. I also have other rectangular vents that fit into the floor only and not up on the baseboard. They required the other type of deflector like almost all of the other deflectors that I have seen.

Quality
This item extending to 25" is difficult to come by so was happy to see FROST KING had the size I needed at a good price. Item arrived in good condition and plastic is sturdier than those I've bought in the past from different brands at higher cost. I've been using their plastic window kits for years and been very satisfied.

Plastic won't withstand the heat!
Plasting is melting and warping after a few weeks of use!

Expensive but it works
The product works well and I haven't had any issues with my natural gas central heat like other reviews mentioned. Fairly expensive at $20 CAD I think a 10$ price tag would be more reasonable.
