|The DM-41L is a perfect calculator simulating very well the original I also own.|
The item i received had a small defect on the screen and Michael implemented a very quick action to get everything fixed.
It has been for me the occasion to see that the internal conception and making of the calculator is at a very high level of quality.
I recommend these calculators, the ratio price / quality is very good.

|I am really impressed by the quality of the calculator which is a result of your big commitment to these products. |
The extended memory, the USB port and the reduction of power consumption are clear benefits over the HP products. In particular, I can finally write and store long programs without fearing that they would vanish every few weeks due to randomly occuring 'Pr Error' conditions. The low-battery indicator of the HP-15C LE doesn't work!
The keyboard is also much better than the one of the HP-15C LE and even better than that of my original HP-15C.

|Thank you for sending the DM15L which is working well. It is a brilliant design. It should end up in a design museum.|
In combination with the Simulator from Torsten Manz it is a practical everyday device.

|These miniaturized wonders are so nostalgic of the original HP's. They operate flawlessly, are actually upgraded|
from the originals in both firmware, hardware, and in quality. These calculators feel great in your hands and have a good weight to them.
These are serious replacements for the originals. If you are still nursing along your old favorite HP,
its now the time to retire it and switch to the new modern, soon to be classic, SwissMicros DM series.
SwissMicros really knows how to take great care of their customers too.

|I have just received the DM16L (serial #135) which I ordered from you last week. I just want to say I am very very impressed.|
It actually feels more solid than my (two!) original HP 16C calculators.
Although I like your original credit-card sized calculators, this full-size one is in a different league.
Very well done, and thank you so much for keeping these wonderful calculators alive, relevant, and hackable.

|Just wanted to let you know I received the DM15 today and I'm really impressed.|
You have done an excellent job creating a faithful recreation of a classic piece of technology,
while putting your own signature on the device that makes it unique and classic all at the same time.
The quality and care you took in building this is evident. Well done!
Jason D., Pennsylvania USA, USA, 2015 Oct. 31,
|Congratulations; a very nice work.|
You have done a great thing in building the HP15 at a size that leaves no doubt about what progress means.
The equivalent in space technology would be a private company sending people to space although the start was done by NASA.

|Many thanks for the DM15, which arrived yesterday. Fantastic Service! It arrived quicker than most post from London. Much appreciated.|
You guys are wonderful and the DM15 is outstanding. An answer to a prayer! I shouldn't say this, but you should charge more. You are seriously under-pricing these.
Prof.Tim Spracklen, Huntly Aberdeenshire, United Kingdom, 2013 March 06,
|This appears to be the coolest electronic device I have seen for a while. |
Thank you for creating this device and making it available to everyone.

|Ich habe gestern noch mit dem kleinen gespielt. Das Ding ist wertiger als man das auf eurer Homepage vermuten mag. |
Bin damit sehr zufrieden. Die Umsetzung ist euch echt gelungen. Habt ihr super gemacht!
Rene, Ebersberg, Germany, 2013 Dec. 12,
|The calculator is really great. I wish I had found out about these earlier.|
Thanks very much.
John Sonewald, Knoxville Tennessee, USA, 2013 July 13,
|Your DM15 arrived today and it's PERFECT !|
Great engineering and software work, thank you very much.
Alessandro Bruciamonti, Pavia, Italy, 2013 Sept. 25,
|Das Gerät ist einfach phantastisch, das perfekte Spielzeug und Geschenk für den Nerd.|
Dipl.-Ing. Manfred Pecha, Wien, Österreich, 2014 June 26,
|The calculator arrived today. Both it and the case are prime examples of expert craftsmanship. I applaud you and your folks.|
I will have many fun calculating hours. Thanks, again.
John Cadick, Garland Texas, USA, 2014 Feb. 24,
|The calculators have just arrived. Thank you! They're great, and the size is just perfect.|
I have the original HP15C and 16C, but they're not as pocketable (or customisable) as yours. The raw titanium casing is a nice touch!
S.J., London, United Kingdom, 2014 Oct. 19,
|I have today received a DM15CC. My reaction? Frankly awesome.|
Can it be improved? Not by much.
Is the size an advantage? Surprisingly yes.
Would I buy additional ones? Actually yes I would - because the DM15CC would be a carry anywhere tool.
Is the price a problem? Not really. If a more expensive say DM42s came out I'd still consider it.
Nigel W., United Kingdom, 2012 Nov. 22,
|My package has arrived yesterday, and the product is fantastic!|
Keep up the spirit and good work, I am your fan from now and will show it to others and promote.
Peter Princz, Tahitotfalu, Hungary, 2014 Feb. 25,
|A quick word to say thanks for an excellent product and excellent service.|
The DM15 works beautifully and I was very pleased when it arrived only 72 hours after ordering.
Alles ganz erstklassig!
Roger Stokes, Caistor Lincolnshire , United Kingdom, 2013 Sept. 02,
|I saw your site while doing a Google search for HP calculator emulators, and was blown away with the work you have done. |
I wanted to drop you both a message of thanks and compliments on the excellent work you've done on these models.
I see these examples as artwork as much as working examples of HP calculators, and I salute you.
Thank you for your interest and detail in these beautiful pieces of technology.
Shawn Tinker, Cincinnati Ohio, USA, 2014 Jan. 15,
|A big huge thank you to all you guys who have brought the DM1x series to the market!|
A less expensive, pocket-sized, and (most importantly) currently produced version of every RPN enthusiast's favorite calculator... yes please!
Ryan McKay, Davis California, USA, 2013 Aug. 06,
|... I recall seeing some notes regarding improvements to the calculators, and from a quick test of the new ones I am actually even more impressed than before.|
Very nice products! And the flip-open pouches in particular are a superb addition, forming what could be a sort of mini-system. My compliments.
D.G., North York, Canada, 2014 Dec. 06,
|Just wanted to drop you a quick note to say that I think your product(s) are absolutely fantastic.|
I received my calculators a few weeks ago and I am speechless with admiration! Many congratulations on your achievement.
I continue to amaze friends and colleagues when I take this calculator out of my pocket.
