This device sort of works but to get accurate measurements you can't really rely on the "click" presser button to engage properly. Let me explain. In an attempt to get a consistent reading the manufacturer is using a "Press" lever that gives an audible "click" sound when you press it firmly enough to overcome the plastic-spring tension. The problem is that it takes considerable force to get it to seat into its click-well to stop the feeler gauge at the proper depth. The good news is you can still see "relative" change accurately as you improve in fitness. That is, the scale might read 20 mm of fat pinch at the start of your first day of new fitness program but in a month you might improve to say 18 mm of fat fold (literally thinner). That shows that you lost 2 mm of fat pinch (which tells you from table look up that your body composition is now 1.4% less body fat - great since for a 100 lb male that's a loss of 2.8 Lbs of solid fat). The problem is that the actual (absolute) body composition is probably higher % fat since that click mechanism takes so much pressure to squeeze the skin fold that it compresses it and artificially lowers the readings. If you were to purchase a more expensive electronic body fat analysizer (which have their own reliability/accuracy problems) then it will usually show a lot more body fat (5% higher body-fat composition than these show). As you lose weight and get down toward an actual real body fat of about 18% the skin fold is naturally smaller and more compact. THEN this will more accurately reflect true body composition (fat %) since there's less error in squeezing that smaller skin fold a bit harder (it compresses less).
But its excellent for seeing relative changes - just don't get too hung up on the numbers being absolutely correct until you are in that higher healthy body fat composition area - 15%-18% or even lower. As well, there's something of an art to pinching the correct location ever time and getting good at repeating it to get consistent readings from day to day.
Note: Scale Weight is not even relevant in fitness. What's important is BODY COMPOSITION - percent muscle and percent fat (Scale Weight=Fat weight + Muscle/Lean Tissue Weight). Preserve muscle since it burns 50 calories per day per lb of muscle (higher metabolic energy demand). So if scale weight increases slightly sometimes due to adding new muscle this is a GOOD THING - don't freak out over the scale weight as the muscle will burn the fat for you automatically. Men should try to get down to 10-15% body fat and women 15-18% body fat (you NEED some fat to keep you alive if you get hurt and are hospitalized and can't eat well.
Simple calculation. If your scale weight is 190 lbs and you are showing 17% body fat by these calibers then you have 32.3 lbs of FAT (190 x 0.17) throughout your body (subcutaneous, organs, visceral) and 157.7 lbs (190-32.3 = ) of muscle/lean/metabolically-active tissue.
