How does the 4.9 Ag version differ from other Lyapko applicators and who is it for? — Lyapko Duett 4.9 Ag 59 mm x 467 mm Massager - Lyapko

The manufacturer does not compare it with other Lyapko models. According to the product card, Lyapko Duo 4.9 Ag is a flat massage device without a roller that can be used on different areas of the body; its dimensions are 59 × 467 mm, the base is made of medical rubber, and the needles are made of iron, copper, nickel, zinc and silver. The device can be used one or two at a time along the spine area, and it can be held in place with a belt, an elastic bandage or a supportive bandage.

The needle pitch is 4.9 mm in the name and the Russian description, but the Estonian card states 5.8 mm (and a size of 53 × 460 mm in the title), so please check the parameters on the packaging. The manufacturer does not say who the device is for; the card's statements about its effect (reflex-mechanical, galvanic-electric, immunological) are not backed by data. Do not use it if you are hypersensitive to any component; since nickel is listed among the materials, caution is needed in case of metal allergy (general recommendation, not a manufacturer's instruction).
