I received mine and works fine. After charging the thumper for 2 hours, it keeps the charge for more
than a day. Cannot see anything inside the box. I know there is a very small magnet, but the normal
spectator will not notice. I like the fact that does not have to be on the table, flat. It can be
held by the spectator in their hand, at any position. No problem with the finishing, because the
price is very good.
