Works as described at a great price
Although the first arrived with a jammed on button, the replacement worked fine.  The price was considerably less than either almost or in fact identical wands.  As described, it came with an excellent case, safety glasses and a convenient plug in charger.  I would have given it five stars but  because of the first shipment being defective and not at this point knowing its longevity.  Also some of the documentation is wrong concerning the battery, if one should want to get a spare.  But certainly worth buying with the Amazon guarantee.
Rating: 4 stars
