Health & Fitness buying advice: what to buy and what to skip

Shopping for health and fitness? Buyzello compares 25 products from 18 brands across electric toothbrushes, water flossers, massage guns, hair dryers, water bottles and adjustable dumbbells, and gives every one a clear Buy, Consider or Skip verdict with typical US prices from $25 to $799.

For electric toothbrushes, start with the Oral-B iO Series 5, which typically costs $99–$149 and stands out for the iO cleaning motor without the extras. On a tighter budget, the Philips Sonicare 4100 Power Toothbrush ($39–$59) is the value choice. A pressure sensor protects gums and enamel from brushing too hard. In water flossers, our top pick is the Waterpik Aquarius Water Flosser WP-660 ($69–$99), best for most people. On a tighter budget, the COSLUS Water Dental Flosser F5020E ($29–$45) is the value choice. Countertop flossers have bigger reservoirs and more pressure settings. Our favorite of the massage guns is the Therabody Theragun Prime at around $249–$299: deep percussion and smart app routines. On a tighter budget, the RENPHO Active Massage Gun ($49–$79) is the value choice. Amplitude (stroke depth) of 12 to 16 mm reaches deeper muscles.

In hair dryers, our top pick is the Dyson Supersonic Hair Dryer ($399–$429), best for fast drying with less heat. On a tighter budget, the Conair InfinitiPRO 1875 Watt Hair Dryer ($25–$39) is the value choice. Heat control protects hair; smart dryers adjust heat automatically. In water bottles, our top pick is the Owala FreeSip Insulated Stainless Steel ($27–$35), best for most people. On a tighter budget, the CamelBak Chute Mag 32 oz ($25–$35) is the value choice. Leakproof lids matter if the bottle goes in a bag. In adjustable dumbbells, our top pick is the Bowflex SelectTech 552 Adjustable Dumbbells ($349–$449), best for most home gyms. On a tighter budget, the CAP Barbell Adjustable Dumbbell Set 40 lb ($59–$89) is the value choice. Pick a weight range that covers your heaviest lifts with room to grow.

We also flag what to skip. We would pass on the Oral-B iO Series 9 if you want value; the iO Series 5 has the same cleaning motor for much less. We would pass on the Therabody Theragun PRO Plus if you mainly want percussion; the Theragun Prime does that for about half the price. We would pass on the Stanley Quencher H2.0 FlowState Tumbler 40 oz if you want a leakproof bottle; the straw lid leaks when tipped and it is heavy when full.
