The Bosch GLM100-23 is a small blue rectangle with a backlit screen, a 100-foot range, and a stated accuracy of 1/16 inch. Bosch gives it two buttons: one to measure, one to round the result. There is no mode wheel or nested menu waiting for you at the top of a ladder.
That restraint is the right call for most people. When we measure a room, a window opening, or the run for a piece of trim, we want a reading we can trust without rereading a manual. The display is large enough to read in a dim hallway, and the body fits in a shirt pocket at 86 grams. It is the one in this group we kept picking up for quick checks because the next step was always obvious.
The 100-foot range covers nearly every indoor job, and the 1/16-inch accuracy is fine for blinds, shelving, and layout. It runs on two AA batteries, which is a small convenience we appreciate in a tool that may sit in a drawer for weeks. If you need area, volume, or Pythagorean calculations, the MiLESEEY D5 does more; for straight distances, the Bosch's simplicity is worth more than an extra mode.
Bottom line: For straight indoor measurements, this is the digital tape measure we reach for first: pocketable, dead simple, and accurate to the spec that matters.
