I'm an engineer and coaster enthusiast and thought this might be interesting. It's really more of just a walkthrough of the though process that goes on in amusement ride design. There's nothing really technical in here.

These are the best coasters I have seen and I do intend to buy a few more in the near future!

clamped it to the specified torq and still my sit post would drop about and inch every ride.
tried some grip paste and i would still get about 3/4 of an inch of drop.
i think the construction just doesn't have enough stiffness and stretches a little.

The recommended age of 9+ is accurate, there is several hundred pieces and hours involved.
The instructions were appropriate for a 9 yr old to follow-more pics than words. Actually they are more patient:)
This is a smaller coaster-just 16ft of track, which is helpful to get you over the learning curve and still have a fun finished product.
Plan to build where you want it to stay-it's not easily transported or sturdy. Plan an alternative storage solution for after take down, the pieces slipped through the cracks of our box. We picked up a small Rubbermaid bin.
Try to save the building plans so you can build again-I have found several of the plans online as well.
Right now we are working with a third set to connect our first coaster.

Disappointed that the holder can not be used for holding the coasters while they are not being used.  The elastic strap(& rivet) on the underside of the holder makes it impossible for the coasters to sit level. So the 8 coasters must sit free standing when not in use. The color is very light.

After using the coasters I have lowered my rating to one star. When moisture (sweating from glass)collects on the coasters it warps as well as stains.

I really like the design of these coasters but they trap water within the grooves and this can sometimes cause bacteria to grow between the grooves and they are difficult to clean. Besides that, I think they are awesome coasters.

Too many coasters. I sent back and received another batch of blank media from Amazon that did work.

Bought it for a gun/ shooting enthusiast as a fun Christmas present, I cannot believe the response a set of coasters received. It looked great and was packaged securely. I cannot give it a 5 as I cannot comment as to the level of which they will hold up, but it I would say it's worth the cost.

I've bought two of these packs in the past month.  I didn't have one coaster from the first pack and have not made any yet from the second pack.  I just got the second pack on march 15 and it's the same as the first.

There are no extra pieces in case they are lost or defective, the claps begin to become to loose to hold the roller coaster together after a week or so of use. It is a great concept, but it simply won't stay together anymore. I'm going to have to glue some pieces together and see if that works. If not, the whole thing was a waste.

The mechanical design here is actually fairly clever; simple, compact, adjustable. The fatal problem lies in the round metal rails that run within the aluminum  u-channel extrusion; mine were not exactly parallel. That meant it was impossible to adjust the trolley wheels for the whole track; it was either lose on one side or bound up on the other.

Furthermore, there's such little clearance under the trolley that without those wheels perfectly adjusted, it would contact the bottom of the track and bind. If I pulled the trolley upward, or turned the whole thing over so it was hanging, it moved freely enough to slide with just a little tilt. But given the track width variance, I couldn't adjust this problem out...so back it went.

I can't figure out why those round rails are there at all...it would seem simpler, lighter, easier to manufacture and less error-prone to just design the rail profile into the aluminum extrusion itself. If you guys at Neewer read these things; fix the track and this'll be great; i'd keep one in my tripod bag (they're that small)

I really liked the way these look, but unfortunately, they don't do the job a coaster is ultimately supposed to do...protect the surface upon which the coaster and drink rest.  The perspiration from cold drinks pools on the coaster, and eventually, makes its way down the edges and onto the counter/table/desk.  Sorry guys, but this is a bust.

Have you ever gone to an amusement park and thought you could make the rides just a little bit better, at least in your imagination?  Well folks, here's your chance.  Especially if you have any love for rollercoasters.  A  little warning though, when I first bought the game I stayed up until 5:00  in the morning playing it so if you buy this game for your kids you might  want to monitor how long they play.  You are set up as the budding Theme  Park tycoon and your initial goal is to attract a certain amount of guests  to your park with a certain level of customer satisfaction (your park is  rated by each guest and the computer keeps track).  If you start from  scratch (the funnest way to play, hands down) you will get frustrated.  Your rollercoasters that you design most likely won't work exactly as you  plan, but it's ok you can fix it.  If you are looking for a family  oriented, non-stop fun PC game look no further than Roller Coaster Tycoon!

Be sure to annotate, when checking out, whether you want ceramic or rubber/foam type coasters. They look a little cheap but server their purpose.

But in a good way.  I've probably spent a couple thousand hours playing Civ (mostly on airplanes and in hotel rooms) over the past few years.  RCT is well on the way to equaling that record.
First, the good news.  It is  a completely absorbing game which allows you to be obsessively interested  in the cost of french fries (or "chips" in the English-English  version), the distribution of ice cream stands, and the correct number and  distribution of benches in an amusement park (you don't want too many  benches -- you want people paying to sit on a ride, not bench-warming for  free).  It is a great lesson in microeconomics.  My favorite solution for  customers whining about standing in line (and they do whine -- individually  and in groups) is to raise prices.  This shortens lines with affecting  total rider load -- since your coasters should be near capacity all the  time.  The ability to go from high-level issues like marketing campaigns  and positioning major new attractions (like of a bazillion types of roller  coaster), to finding out what one individual customer thinks about the  drink stations is challenging, fascinating, and (I tried not to say it)  cool.
As a game, it is first rate.  I don't know how they get this kind  of performance on my over-the-hill-computer (an old P200, without MMX), but  I'll take it anyway.  I tried the downloadable demo on my PIII-500 at work  and it was much crisper and responded better.  (Am I crazy to think about  spending $1500 on a new computer to play a $29 game?)
The problems are  small by comparison to the enjoyment of playing.  Like most games, it needs  better "help" functions when you are learning it.  It really  needs an off-line coaster builder and tester.  In the real world you can  engineer new amusement rides without actually building a full-scale model.  In RCT the only way to test new coasters is to build them and run them in  real time.  If you make mistakes it can be ruinously expensive to tear them  down and fix them.  Sometimes it is hard to place large, pre-made features  because of land, trees, other terrain features, and other rides.  The  interface tells you cannot build something because of a tree, but it is not  always easy to tell which tree.  My screen is a 17", and I wish it was  bigger for this game.  I can tell there are some small things going on, but  I have trouble making them out.
The only major flaw has been that the  game crashes frequently on my system running Windows 98.  I've loaded the  latest patches, but it still fails once in awhile, and ALWAYS crashes EVERY  time I click on the "pause" button.  I know this is some  diabolical combination of factors in my Win98 installation, but I may never  figure it out.  Pausing is for wimps, anyway.
The first night I played it  (after sending my kids to bed so I could get near it) I was up three hours  after my bed time.  This is what makes it worse than Civ 2.

This is NOT a thirstystone coaster.  It does not soak up water, when I pick up my glass that has sweated water, there is a pool of water still on the coaster.

your coasters stick to the bottom of the glass with a little  sweat. i am not impressed. if it did not cost so much i would send them back, i live in the D.R. mail is double going out then coming in. you can credit my VISA
