(+) 1. The VibraLITE 8 sports arouses the vibrating alert as well as the VibraLITE 3, significantly stronger and longer than the Casio RFT 100-2VER or Timex XL. The optics could indeed removed as "elegant" mean, but really pretty, I find it not. The numbers, however, are really nice and big and easy to read even at night.
The large and wide forearm / wrists "ergonomic" easy preformed plastic bracelet looks more like a bit of a medical device. With my rather wide 20cm forearm / wrist circumference, keep your fingers the preformed rather stiff-rounder and for wrists transition region from the bracelet at the clock then mildly uncomfortable. For forearm / wrists with less than 18cm circumference (Manufacturer: 12.5-19cm) but the bracelet form should rest a bit more appropriate.
So the scores VibraLITE 8 with their prima-read figures and strong vibration, which is, however, also clearly audible. With flexible Velcro strap and perhaps somewhat sportier look me this clock would then also convinced. So I have (with my larger wrist circumference) probably still fall back now on the VibraLITE 3 - in spite of their small numbers to me.
(-) 2. Casio sports referee watch RFT 100-2VER the clock stops while fully what it promises! For wake people (eg on the sports field and in it or out) is the gently-clear vibrating alarm super good and sufficient tangible! I, however, wanted to "abuse" as an alarm clock. Also the vibrating alert (usually) is sufficient and arouses people with not too fast asleep well on. However, he turns once after pulsed 10 seconds, and is thus for heavy sleeper maybe not quite as recommendable ... (?) And the really quite quiet beep I barely heard. Have returned the clock on Ebay. For people who wish to have a near-silent vibrating alarm, it is (and the Timex) the more correct.
(-) 3. Timex Gents Watch XL Analog plastic T49851 - from vibrating alert her as gentle-clear and only 10 seconds pulsed like the Casio sports referee watch RFT 100-2VER. After all, can be at the Timex alarm three times briefly in succession to adjust, so you can let yourself Snooze. Otherwise, Timex has also at night easily readable digits and looks pleasing. The bracelet is relatively smooth and either an estimated wrist circumference up to 20 cm. For all sporting purposes the clock is fine, however, to me is the relative softness of the alarm to wake up not sure enough - I send back the clock.
(+) 4. VibraLITE 3 Army look - from vibrating alert forth much stronger and with about 18 seconds longer than pulsed at the Casio RFT 100-2VER or Timex XL. The ordered by me (Army-) optics of VibraLITE 3 then I really like in reality! However, the time digital display quite small. Without my reading glasses (+2) I have at night so no chance to recognize the Ziffen. But her strong vibrating alarm woke me up just fine and safe. In addition, can be a 2nd alarm set so that it again later "nachweckt". The Velcro strap is snug enough, and for 21-22cm wrist circumference pending. Despite the small numbers to me personally I will keep it now.
