"I received the board this morning @ 10am....Very prompt...Very impressive Clever board....I will have no problem when it comes time to get another board from you guys. Its about time someone finally got it right!"

"The Pewatronic GM50 and the case for the GM40 arrived well thank to the adequate packing! Overall impression after lots of comparison tests:

The project GM50 was worth it - the Pewatronic Grandmaster 50 and its 64 bit processor ARM 8 (1.2GHz), 1GB RAM and 32 GB flash memory is currently the strongest in series produced chess computer in the word. Its design in tournament size is timeless - its operation and menu guidance per touch screen is very up to date and currently unique."

"The playing strenght for a chess computer is enormous. But it is easy to adjust the own skill level, to play interesting matches they challenge but do not discourage. Thank you very much for this great device.

On the topic of customer proximity - There you are in the first place. You can be very proud of that."

Richard Popp, DE (Thursday, 3rd of May 2018)


"Thank you for the prompt delivery and the careful packing. I would describe this chess computer as very noble and it exceeds my expectations. A big compliment to you and your colleagues who made this noble item. I'm pleased now to play on the balcony (thanks to the powerbank), if the pollen event is over."

"By the way, what a beautiful chesscomputer you made!!
I have several, but this is really a beauty!"

"Maybe you remember, at the end of last year I bought a 'Grandmaster'. I would like to thank you very much for the very friendly and competent purchase. The 'Grandmaster' is an extremly beautiful chess computer with a simple and very noble design, by that I had a lot of fun in the meantime.

Heinz-Peter Hoier, DE (Thursday, 18th of January 2018)


"First I want to thank you for the really nice transaction. The 'Grandmaster' arrived today without any issue. The workmanship and quality are uncomparable. It is really fun to play with the 'Grandmaster'. On a scale of 1 to 10 I would give it 11 points. A top device that in no way needs to hide from its competitors. Keep it up and thumbs up to the whole team that made and developed this chess computer. You are welcome to publish this review on your website. I would be delighted..."

Stephan Fensky, DE (Thursday, 23th of November 2017)


"Yesterday the 'Grandmaster' arrived. In the evening I familiarized with the menu and also played 2 games. (Stockfish level 5 was already a hard opponent)

 

It is really a pleasure to play with this device. The beautifully made wooden board and the noble chess men match perfectly. The chess men are good weighted and made with attention to details. Also the display is nice and the menu navigation is intuitive. The sounds are well chosen and not intrusive. For me also very important is the current evaluation (+/-), pretty nice that it refers to material and position. The player name was already entered - thank you.

 

As I can see by now the engine plays well balanced, it means it plays constantly the set level. For example other engines play 5 moves with full strenght and at the 6th move they sacrifice a piece to compensate the level. That bothers me as player. Alltogether a very beautiful chess computer, perfectly made, with a great fun factor."

"All arrived savely! I just made a test game and everything seems alright.

As far as I know your company manufactures these chess computers. a big compliment for it about the usability. All is easily understandable on the first trial. I had many chess computers before but rare one is usable so easy."

Wilfried, DE  (Thursday, 2nd of March 2017)

 

"I'm really glad about this device! It's not only looking fantastic, it's outstanding to use and plays very good, if needed. One also can adjust the skill level to the own skill."

Wilfried, DE  (Saturday, 11th of March 2017)


"It is alright. No issues on the case and computer. The first start yesterday evening was successful.

This morning I tested an ANKER powerbank, works also. By the way it's a very beautiful chess computer (exactly as the pictures show!)."

Uwe Romig, DE (Friday, 20th of January 2017)


"I would like to thank you very much for the good service and the top advice - Customer satisfaction guaranteed!

I already played a few games in different game options/mode. It is really a great pleasure to play with the 'Grandmaster' and it's the better option than sitting in front of a computer screen."

Martin Valt, Thailand (Thursday, 27th of October 2016)
