Just purchased my 3rd copy, very challenging. Looking for the next version.

I like this DVD. It has a concise instructor, good modifications, and a very lengthy step program (over 40 minute of step).  The choreography is fun and interesting, but be careful, this is advanced.
I workout to different aerobic DVD's and step happens to be my favorite (at home) because I can get a good workout and keep my heartrate up.  I would consider myself an intermediate stepper based on the amount of time I step each week (over 2 hours) and the length of time (more that 3 years).
I found this difficult, but, I appreciate a DVD that is a challenge.  It gives me something to work toward and a feeling of accomplishment when I complete it correctly.
You will like this one if, like me, you like a challenge and to step for over 1/2 hour.

This is an extremely challenging book. It forces you to consider your relationship with God, yourself and others based on 21 questions Wesley asked the Holy Club at Oxford. I went through it with a small group. Part way through I realized I need to go through it again. So much to absorb in 21 days.

Great study and is personally challenging.  The video tapes enhance it for a small group.

I bought this book several years ago, but I think it was a little too hard for me to play at the time, and I put it away. Once in a while I bring out older purchases again, and I most often find that I play the pieces out of a book better than the last time, I had it out.

Recently I brought out this Shearing collection, and I started from page one. As I turned the pages, I soon realized, as 'A Customer' also wrote in another review of this book, that these arrangements are excellent! They sound great, they are varied, and they are challenging enough that you feel you grow and learn new stuff as you go. The arrangements are definitely not for beginners, but if you have a couple of years of serious studies behind you, then I think you might enjoy this book as much as I know I will.

Good level of difficulty - I like a challenge but not making pencil marks. Love the spiral binding. Each page has two puzzles which makes them adequately large.

This puzzle is one of the most difficult puzzles I've ever seen....

It's not Sudoko, and it's not rubik cube..
It's a new type of puzzle which is really intersting and challanging.. I really like it... :)..
If you are clever enough I advice you to try it...

But be careful while you are playing with it.. I recommend to remove one of the corners and put inside the cube some Vaseline, otherwise it might be broken while moving

More challenging than first one.  Play it often without being bored.

Challenging, which was great because I am very good at puzzles. I finished it about a week and it is beautiful. I wish it was available in 2000 pieces because I want to use it as wall decor, but it is still really nice hanging up. Also I think making art into a puzzle allows you to get to know the piece in a way that you never would otherwise because you are studying the details of the work. This was a lot of fun, and I have a deeper appreciation for Klimt.

This is fun, and much harder that you would first think. Very challenging and fun! I played with my 6 year old son, and 16 year old sister. We had a blast and each challenge was different and fun. Very engaging. We all enjoyed this very much

This game was awesome.  The graphics are stunning as are the effects.  It is very difficult, but very rewarding once you have beaten it.

These are very challenging puzzles and I think even tougher than the Black Belt ones.  The main structural difference is that the maximum length of the sums is 7 with the Brown and 8 and 9 with the black.  I'm able to finish about 2/3rds of these without help versus probably 3 out of 4 of the black belt series.  Still, the puzzles are very enjoyable to solve.

Extremely challenging. Not for a raw beginner unless you view it a few times first and go slow to start! Many different routines to choose from so it doesn't get boring.  Great for upper body strength, core, and back which are all weak on me.  I recommend this DVD highly!

With 2 Dozen tracks and a dozen cars this is an excellent racing game.  There are many awesome stunts you can learn and some are not so easy.  The Graphics are not as bad as everyone says and the cars look great.  The gameplay is great making it a tough and challenging game.  I recommend this to someone looking for something a little more challenging.  It will get frustrating if you aren't patient!

Challenging. Bold. Full of scripture. There isn't much else I'd say about this book except read it for yourself! Thanks
