The discs are well made and appear to be of the same thickness as alternatives.  Unfortunately, at 1/2", they are too thick to use in tandem (as intended) on my 50's Sears table saw.  I've no idea how they work on newer saws.

The movie image itself is very acceptable - clean and sharp. Unfortunately the somewhat elaborate packaging is among the most impractical I have encountered, with loose discs that insist on falling out at the merest touch. Further, I have some concerns about the discs' durability. The three discs are covered in tiny blemishes and scratches and, while I will not go so far as to say that they are 'damaged or defective', they certainly give the impression that they may deteriorate over time. Rather concerning for an allegedly 'prestige' product.

Never heard of the brand before but they work well from the discs that I've burned with 'em. The writable surface is also a bonus

The product is excellent and arrived in a reasonable time span.  I am about 1/3 of the way through the discs and all have been in excellent condition so far.

These discs have been up for 2 weeks, and so while I can't say with certainty that they are going to eliminate the problem, i can definitely see how they have great potential to do so!

First off, as others have pointed out, these are beautifully crafted discs... excellent quality that should last many years.  Assembling the discs is straightforward but easy enough.  Be careful with your fingers... the discs can be sharp on the laser cut edges.  I assembled all of mine without gloves without a cut, but you want to be careful anyway.

I was concerned about putting up anything that would take away from the look of my red saltbox colonial, so I was pleased with how nice these look, and how they don't draw attention to themselves, but just to their actions - confusing I know.  What I mean is that the mere presence of these disks doesn't look out of place.  Unlike a bird balloon or a decoy owl that clearly looks like "hey - there is a fake owl on that house", these don't stand out by themselves.  However, with the slightest breeze and some sunlight they create a light show of spots flying around and draw attention to their movement.  Almost like wind chimes.  This is why I think they will totally do the job!  They are highly effective at causing distraction during the day, when the woodpeckers come out to play!

UPDATE:  So it's now been 5 months or so since I installed my first set of discs, and I just bought and added a second set.  My bird concern has always been about the woodpeckers who seem to live all around me and who last fall made swiss cheese of my trim boards and barn siding.  Because I have a seperate barn and an off-angle garage connected to the house by a screen porch, the original 8 sets didn't quite cover the whole house.  On the 20x24' barn I hung one set on each corner and that has worked perfectly.  On the house I was only able to easily mount one off my electrical electrical wires (which was where most of the damage occured) and the rest i placed in trees near the corners.  This actually seemed to work great, as I check the house all of the time for any new pecking.  Despite constantly seeing the woodpeckers flying around the property, and hearing them drumming away on nearby trees, there was no new damage to the house - until last weekend I noticed 2 new peck spots on the back of the garage - the one corner of the house where I had no discs in site.  I immediately relocated one from a tree and hung it from a spotlight on that side of the garage - and since then no new damage.  I figured since these discs have been so effective it was worth buying another set and really loading up the area.  I like having them both on the house, and in the smaller ornamental trees I have because I think it helps keep the woodpeckers not only off the house, but also away from it whereas before they would perch in the trees, then fly over to do some drumming and if startled they'd seek refuge in the nearby trees.  Now they have a longer flight to get out to the edge of the property to avoid the discs. Considering what they did to my house in the fall (see photo) and how many woodpeckers are still around and drumming, these discs have without a doubt worked!

The first disc in this series does not play.  I feared the remainder would likewise not work, but they seem to be playing fine.

Both disc have been remastered and are very good quality. The music goes very well with the disc. The extras have a lot of valuable information.

One of the dvd disc has a noise on it at the beginning and intermittently  through out . Have not watched the entire collection to see if others have the same problem.

the first disc would not down load, but the 2nd and 3rd disc are good

These seem to be well-made and are easy and smooth to operate.

The colored plastic disk cases allow the disk to be housed and protected properly. The cases are made of an acceptable quality material that snap together when closed. The colors are rich and the plastic appears to durable.

Better care should be taken to make sure the discs which are made on demand do not have scratches, certainly has put me off ordering on demand. It was a present for an 80 year old man, who should not have had to race through the entire collection to see if they would play or not.

So far everyone of the discs are without any visible flaw. To pack all the discs it got rather crowded in the lovely case. Still it is excellent to have for the price I paid for it.

Bought these cases to make room for our DVD collection. However, they are not as well made as their older versions, which I cannot find anywhere. Do not hold the movie sleeves so we had to improvise. I am not entirely happy with my purchases, but they will do until I am able to locate a better product, them most likely will give them away to someone who could use them for their CD collection.
In a word they are not suitable for DVD's and should not be advertised as such.

I had the same problem.  Despite using two different colors on the discs, the content was identical.  This manufacturer has a problem.

Well packaged and fairly easy to install.  Only negative was clear acrylic discs were worthless, but easy to buy stickier ones.

Simply well done. Worth the money. I recommend this set of discs to anyone. Beautifully photographed and produced. Great job.
