The concept is great. You must have a lot of brick exposed for this to work. The brick on my house has minimal surface so these did not work for me.

I really like the concept and idea a lot.  Whether you can use these on your vehicle may vary. Many car speakers are mounted so differently, you may not have room for these, or all the rings if so. You won't know until you see behind your panel to get an idea. You may also need to modify the factory speaker mounting or surrounds to adapt these. Or modify the rings themselves.  Be prepared for some slight modification, but they appear to be quite better than what most factory speakers have going on, if any. If you can, search the internet for how to's for your specific vehicle. See if these seem plausible for your application before ordering. Also, I would advise you to prep these rings with some spray on 3m scotch guard before putting them in your door. They are open cell foam and may retain moisture.  My reason for giving 3 stars then is because I was sent the wrong size. The package of the product had conflicting lables. I wanted 6.5"s.  I received 5x7's. I didn't have time to acquire the proper rings before the install, so I went on without them. I would have liked to use them, and If I ever plan on taking these doors off again, I may attempt to try these again. Though I may try a different vendor to assure I'm getting the right ring.

What a great concept product!! However, I agree with many of the previous remarks in that this product needs much work to become more mainstream. I really wanted to keep the card..really. However, too many compatability issues with vendors and the push button that cycles between cards stopped working.

A good quality product that can offer a solution to the Transformer/Dongle/Brick problem. There are other solutions and you should be aware that this is a three dimensional solution that if your Bricks are of a certain dimension you will not be able to fit them on this.

It works, and the concept is awesome. That's the positive side. The press mechanism is very flimsy and bent after about the third brick. I straightened it out and continued to use it, but ended up straightening it out after every press. I will have to weld something stronger together before I can use it again.

Great concept, I can't stand suction cups. I checked negative reviews and you have to get creative with the diagonal portion that can scratch your dashboard. I used some foam padding (like from portable AC exhaust window install) and put the adhesive side up (no glue on dash). Also, when tightening the screw it can increase tension where these diagonal edges meet your dash, increasing chance of scratches/grooves the tighter the screw. In summation this product is great IF applied with care. 5 stars if there wasn't some Macgyver'ing involved.

Good points: The ceramic stones and tiles are lovely. The cardboard pieces for building the interior model structure are well designed.

Problems:Watch out if you have to pay for shipping-- it can be a lot because it's so heavy. I got mine on Prime, so the total cost was about $88. The instructions are insufficient. There are few pictures. You will need to shape the angled bricks yourself by sanding them away-- they are just rectangular. There is no plaster or instructions to make the rocks and landscaping. The color instruction sheet is just general to all the kits. It looks almost as if it is incorrect instructions, but that's just the way they do it.

Beware there are a lot of the bricks called for that are NOT avaiable anymore from Lego.  So if you are like me and don't already have older discontnue legos to choose from you will be out of luck trying to build a lot of these..Sending it back because most could not be built

It might seem small at the beggining, however once you start, you realize there are a lot of pieces. A lot of fun building it and a nice start in lego world.

Maybe the only recommendation for new releases, is trying to make the One world trade center a little more sturdy in the middle part.

This is a classic example of a wonderful concept executed very poorly. The finished project looks awesome, but it took several hours of sweat and tears with many instances where we almost threw in the towel because the truck engine portion of the project (which Kinex has tried to model similar to LEGO concept) is extremely poorly engineered. The yellow brick pieces kept coming off because the chasis portion is attached to the body at only two points. The driver won't fit on the seat, and at many places the bricks only attach at one joint, resulting in many hours of frustration trying to keep them together. Bottomline - Kinex should have done a better job at engineering and designing this product, plus they should have tested thoroughly before launching in the market. And there is no way even a 10 year old (let alone 5+ yrs age limit on the packaging) can have enough patience to deal with ill-fitting bricks, when many adults would be frustrated dealing with such a poorly designed product.

This idea  is great. Everyone's jaw hits the floor when I take the playroom from disaster to walkable in less than 30 seconds.

I could give it three stars since one of the chords broke within a month, but I can't say if it was due to poor materials or crazy ass kids. I was able to fix it, however and have even developed a strategy using the design to bring smaller pieces to the middle. Making it easier for me.. err, I mean my kids to find them.

I also want to suggest a more neutral color.maybe white or taupe. It's especially hard to find transparent peices with the dark blue.

The concept of this product to remove the soot and smell from old fireplaces is wonderful.  It has greatly improved the appearance and smokey smell of my 60 year old fireplace.  I have a rough fieldstone fireplace of about 35 sq' with cement holding the stones together.  The gallon can says it will cover 40+ square feet, but when I tried to remove it, it was next to impossible!  I called the manufacturer and they recommended applying an additional gallon which I did.  This was a bit better, but it still took me 8.5 hours of painstaking labor to get it peeled off.  I probably should have used a third gallon or 3X the recommended amount!  Be forewarned - if your fireplace has a rough surface, you will need MUCH more of the product than you think!

The concept is fabulous.  When you can get it to work well, its great.  But the batter has to be just perfect for the results to be worth your effort.  Plan on some major prep and a long breakfast.

I was worried it would not hold up to weather attached to brick but it has done great

It's a great concept and a lot better than the regular Foam pads but could be a tight fit depending on your build.

Like many reviewers mentioned before, it only works if you can attach the ends to a wall or fence or support it with bricks or other heavy duty items from the back. Otherwise the included stakes are too short to hold the flimsy panels. But once it is installed it does what it supposed to do, in my case covering up an AC unit in my back yard.

It is a great idea, but the plastic is too flimsy.  They need thicker plastic.  I bought six and three buckled and started to lean over.  I used petunias.  They look great if it wasn't for the buckling.  Don't use vincas.  They don't work well in the tower. You can make your own which I did out of wire roll and weed barrier material.  You can find directions on the internet.  It holds up much better.  I would buy again if they remake the product with thicker plastic.
