Pros: Very attractive new design. Pieces are beautiful and with magnetic bases. Pressure sensitivity when moving pieces is just right... very little pressure needed. Superb display and menu design. Saves games for review and analysis. Great selection of levels. Nice compact size. I'm an 800. -1200 ELO casual player and beat it on my first try on "Fun Level 1" with "perm. Brain" turned off. It was a very fun long game and gave me a challenge. Two extra queens are included. The price is great for such a nice product. This order was filled by the great team at Chess House who have always been superb! Their customer care is always excellent! I love this product and highly recommend it for all levels of chess players.
Cons: A minor preference on my part - I would have liked a storage compartment on the bottom for storing pieces, but the excellent slim profile may have kept that from being a possibility. I do love the slim design after all and a nice drawstring bag is included for storing the pieces. I have no other cons whatsoever.

c'est un beau petit jeu, très performant, pour un joueur moyen c'est tout un défi et c'est très motivant, si on veut pas s'ennuyer et qu'on a l'esprit de compétition c'est l'outil qu'il nous faut et on en a pour notre argent.

I agree with everything in Chuch Moody's 10/19/23 review. I have nothing of substance to add to his judgments about the Millennium Chess Genius Pro 2024 model M815.

But I will repeat once again what many of the reviews on this site say: Chess House customer service is second to none.

Perfect for my particular needs. Saves up to 12 games. Highly portable [use a plastic 8.5 x 11 inch file box w/ handle for transport]. Strong magnets. Concerns? Info from THEIR site is still minimal on this model. Chesshouse is the best!

First off, Once again my whole experience with the purchase of my new Millennium Chess Genius Pro 2024 from Chess House has just been fantastic. After checking prices online, I found that Chess House indeed had the best price. I Placed my order Friday the 13th and received my Merchandise on the 16th. Wow, that was fast!! My Chess computer was well packaged and arrived safe and sound. After playing several games I was able to adjust the playing strength to match my own and I just had a lot of fun with this new machine. Here is my review of this new chess computer.
The Millennium Chess Genius Pro 2024 model M815 is certainly a fantastic upgrade from the standard Chest Genius Pro M812. It has some nice bells and whistles that make it an absolute joy to play. A color LED readout lets you clearly see everything that is going on. The chess pieces are a really nice new design that look and feel good, and yes they included extra queens. The pieces are magnetic with a nice magnetism that is proper for their size and weight, and the black pieces have a gray offset in their color that makes them easier to visualize on the solid black squares. Operation is simple and straightforward, and most will only need a brief review of the owner’s manual to get started. You can now save up to 12 games and replay them anytime. You can fully adjust the playing strength, along with a new feature that allows you to pick from several styles of play which makes this new Chess Genius Pro Perfect for the new beginner as well as seasoned pros. I found that taking back a move has been made easy and straightforward on this machine, a feature I find very refreshing since I make a lot of mistakes. The computer will now even offer you a draw or resignation, which is nice. You can also choose different chess piece designs for your LED readout. There is a solid on/off switch separate from the on/off button that is thoughtfully recessed to prevent the power from being accidentally turned off. This also prevents the unit from being accidentally turned on when running on batteries which is a feature I particularly like.
I played the old machine versus the new machine. They're both rated at the same strength and The game ended in a draw. Also, when you win by checkmate, you are rewarded with the sound of a cheering crowd how cool. Millennium is releasing the in-depth Detailed manual next week, so I'm looking forward to that. Below I've included some pictures of a comparison of the old Chess genius pro on the right and the new chess genius pro on the left and a photo of the new pieces with the slight gray offset Which makes them easier to see.

In conclusion, I personally really like the new Millennium Chess Genius Pro 2024. The folks at Millennium have done a fantastic job at keeping things simple and easy while giving a much-needed upgrade to the old model, and at a price we all can enjoy.
