The product is good but The adaptor provided is of very low quality. The product doesn't have battery and is in convenience to user. It does not function smoothly as video shows. The user manual contains only one page and is with insufficient information. Package contain s only one stencil and 3 very short length coils which is highly insufficient for the begineer. The user would be happy if adequate coil is provided and a CD of activities and detail user manual are provided in package. This will increase usability and consumable order.
