How much does a body composition tester cost

Depends on what it is used for. If it's for beauty use, 2W or less will be OK. If it is fitness, then in INBODY, Tongfang, Jie Wen pick inside, the price from 3-8W ranging. If it's for medical use, it's basically 10W or more. If you like the gorgeous appearance, I personally recommend INBODY 520, about 8W, if the pursuit of cost-effective, then recommend the Tongfang BCA-1B and 1A, much cheaper than INBODY.
