Newer reviews can be expected to be ongoing projects, with minor additions or corrections.

Note: When I rate stuff, a 10/10 does not indicate perfect in an absolute academic sense, but as in (at least) as good as could be expected at the time, minor flaws allowed. For portable devices typically limited by the size and weight. Value for money also counts. An electronic device that got a high score in 2005, most likely would seem like pure trash ten years later….


  • Honor Watch ES versus Honor Band 5

    Got a Honor Watch ES-21C to replace the Honor Band 5 I have had for half a year.

  • The EASY way to make a C# Windows.forms app really per monitor DPI aware

    As posted in another post, many apps have problems with windows scaling.

    See these screen-dumps from Windows lengthy guide that was found here

    UPDATE 2020. After Windows creators update, they made things slightly more complicated, sorry…

    Here is a reasonably minimalistic approach. You will often just need code like this:

        public partial class Form1 : Form {
             public Form1() {
                 DPI_Per_Monitor.TryEnableDPIAware(this, SetUserFonts);
             void SetUserFonts(float scaleFactorX, float scaleFactorY) {
                var OldFont = Font;
                Font = new Font(OldFont.FontFamily, 11f * scaleFactorX, OldFont.Style, GraphicsUnit.Pixel); 
             protected override void DefWndProc(ref Message m) {
                 DPI_Per_Monitor.Check_WM_DPICHANGED(SetUserFonts,m, this.Handle);
                 base.DefWndProc(ref m);

    You will need to obey a few rules, but often it can be implemented in existing code in minutes!

  • Automower 435X AWD, Husqvarna, review.

    This Automower 435X AWD is an upgrade from my 330X, See review here.

    Overall: 9/10. Hardware: Fine. Software: Improved, still unpolished!

    This is both a continuation of the previous Automowers and a fundamentally different approach

    Updated 2020-04-29, Some stuff are fixed with newer firmware.

    2020-08-05 This review has evolved over time from an early review, with several updates, so bare with me, that things are not in a straight chronological line…

    2020-09-05 Updated with new stuck-bug

    Continue reading...




Newer posting are in English (well sort of, bare with me, non-native…), some over five years old just a blunt copy of the texts in Danish.

Layout – and perhaps more translations (hopefully) will be improved later.


Collecting of old stuff started May 2015. Entries are generally attempted dated with¬†original stamps, even if they are somewhat updated since, several reviews have been ongoing ‘projects’.
