OMRON BF511 Full Body Composition Monitor with 8 Sensors - Tracks Weight, Body Fat, BMI, and More - Family-Friendly Scale (from 6 Years) - 150 kg / 330 lbs Capacity

Firstly excellent scales - simple to use, good price and very repeatable measurements. Weight is a perfect match with the scale at my doctors and is precise down to 0.2 lbs / 0.1kg. Body fat, etc is very difficult to measure accurately with scales like these that rely on conductivity but with both the feet and hand sensors it has the best chance of accurate measurements. However, yesterday I had the opportunity to find out exactly how accurate these scales are. I had something called an DXA (or DEXA) scan which is a form of mini XRay that tells you exactly how many grams of fat, lean tissue and bone you have in each limb and AFAIK is the most accurate way of working out body composition short of an autopsy. PS: it's not a good idea to mess around with XRays for none critical conditons so this isn't a recommendation of DXA scanning but given I have had one it does tell us how accurate these scales are... It'll probably be obvious from these numbers that I'm not fit (yet) so don't laugh - I'm working on it :) Background info: Male, 34, Caucasian Height: 177cm Weight: 81.9kg Body Fat: 29.6% (Omron scales), 32.8% (DXA Scan) Visceral Fat: 11% (Omron scales), 8.8% (DXA Scan) Lean Mass: 33.6% (Omron scales), 63.0% (DXA Scan) So, the body fat percentage for me at least was very accurate. The visceral fat was an overestimate but not by a huge amount. The Lean mass is miles off, however I think there's a difference in what's being measured here. I believe the Omron scales are estimating muscle whereas the DXA scan is measuring all lean tissue (ie: everything that isn't bone or muscle = organs, ligaments and muscle). Overall I'm very pleased with the accuracy and repeatability of these scales and for measuring relative changes in body composition they should be very helpful. Good stuff: * High accuracy measuring weight and total body fat percentage. * Decent measure of internal body fat (the really bad stuff). * Simple to use - step on to get your weight, press the profile button on the handle to measure everything. * 4 profiles/users * Shows current readings and last readings for comparison * Measures in kg and lbs to 0.2lb and 0.1kg accuracy * Quick ~5 seconds for measurements * AA batteries (included) * 3 year warranty Bad stuff: * Only remembers last measurement (seperate memory for each profile/user) so need to keep a pad of paper to track long term changes * Electrical conductivity measures can be heavily affected by water content so you really need to way at around the same time each day under the same conditions - ie: drinking water before measuring changes the results. * Doesn't send results to phone/computer/whatever - personally I think this is an advantage as it's simple and does exactly what you need but some people really want an app on their phone *shrugs*.

Excellent quality and accuracy. I’ve measured the results against the medical machine at my gym and it was a like for like result. Didn’t expect to be this accurate for the price. Tested another brand before this one and the results were way off.

As an ex-personal trainer, body composition is very important to me. My fiancee is a fitness finatic as well so this was a must for us...especially at this price. My youngest step daughter has also joined in with the monthly 'weigh-ins' after seeing mum and step dad doing it. I think it is very important for her to understand that to a certain extent, your body mass is not important; it is what that mass is made up of that matters. This Omron monitor reads everything I need to know to reassure me that my training is still being effective and that adaptation has not taken place...so my results should remian positive.If your not to bothered about body fat etc...it also has a weight only function! The display is very easy to use and what a bonus that you can store 4 peoples stats in it to make it even quicker to get your reading; the machine also remembers the previous weigh-ins statistic for quick reference...bonus =) Overall a great bit of kit that im sure the whole family will use for years to come. My only negative which justifies the 4 out of 5 is that it does not read water mass / percentage...I think it is important to know you are hydrated or if you want to be negative; dehydrated. PLEASE REMEMBER THOUGH...WEIGHING YOURSELF CAN BE OBSESSIVE AND LEAD TO EATING DISORDERS...FACT!!!; PLEASE BE ESPECIALLY CAREFULL IF LETTING CHILDREN USE THEM!!! ALTHOUGH I USE THIS MACHINE MONTHLY; AS A PERSONAL TRAINER I ONLY WEIGHED / ANALYSED BODY COMPOSITION OF CLIENTS EVERY QUARTER...THIS IS SUFFICIENT TIME FOR VISIBLE RESULTS AND SHOULD KEEP YOU MOTIVATED TOWARDS YOUR FITNESS / HEALTH GOALS. But most of all...Exercise should be fun, not just goal related. If you enjoy it and persue it, results will come in time; internal as well as external.

Works great only missing an app to connect to my phone and share the results with my nutritionist

Looks great and work even better. But I have used it only once since I’ve just got it. The batteries are included.

La Omron BF-511 è un'ottima bilancia impedenziometrica, probabilmente la più accurata ed affidabile sul mercato sotto i 100€ (io l'ho acquistata per 73,49€, approfittando di un'offerta lampo. L'articolo aveva subito un notevole sconto anche durante la settimana del Black Friday). Non la definerei esattamente facile da usare: la procedura per una misurazione completa, e quindi non del solo peso complessivo, ma anche della composizione corporea, dev'essere eseguita molto scrupolosamente, attenendosi alle istruzioni ben illustrate nel manuale fornito (disponibile in diverse lingue, tra le quali l'italiano). Per una buona attendibilità dei risultati, occorre effettuare le misurazioni ogni volta allo stesso orario, a digiuno, lontano da allenamenti intensi, con palmi delle mani e piante dei piedi puliti (per il corretto funzionamento degli elettrodi) e rimuovendo eventuali anelli, gioielli o piercing (tutto questo è spiegato molto accuratamente nel manuale d'istruzioni). Nonostante questi accorgimenti, è possibile notare una differenza nel risultato della percentuale di massa grassa anche dello 0.2 ~ 0.4 % tra misurazioni ripetute, per questo consiglio di eseguire almeno 5 misurazioni per poi calcolarne la media (questo "problema" non si verifica invece con il peso complessivo, che è quasi sempre esente da variazioni tra misurazioni ripetute). La bilancia è molto solida e robusta, tuttavia, nel manuale d'istruzioni sono indicati vari accorgimenti per una corretta conservazione del prodotto, per esempio: tenere l'articolo lontano da fonti di calore ed in posti asciutti (non umidi) ed evitare colpi, cadute o brusche vibrazioni. I parametri misurabili comprendono: peso complessivo, BMI (Body Mass Index), % di massa grassa, % di grasso essenziale/viscerale, % di muscoli scheletrici e calcolo del Metabolismo Basale (fabbisogno energetico giornaliero indispensabile). La bilancia permette di memorizzare fino a 4 profili differenti (per ciascuno dei quali è possibile impostare sesso, età e altezza), con la possibilità per ciascuno di verificare i cambiamenti rispetto alla misurazione precedente per tutti i parametri. Se si desidera monitorare il solo peso complessivo, non è necessaria la creazione di profili, ma, in questo caso, credo che l'acquisto di questo prodotto sarebbe sprecato. Concludendo, ritengo questa bilancia la scelta migliore per coloro che desiderano monitorare i parametri più importanti della composizione corporea, senza interesse verso altri dati, come % di acqua, misurazioni per segmenti o età biologica, disponibili invece in altri modelli più costosi. Dopo estese ricerche, sono arrivato alla conclusione che si tratti della bilancia impedenziometrica più accurata nella fascia di prezzo sotto ai 100€. Assolutamente consigliata.
