Fast delivery and product seems to be of high quality. It is a bit larger than I anticipated but looks to be easily used. 3-7-24 UPDATE This product is extremely well built. Much easier to use than those egg shaped ones. I will advertise this with others. The joules is as advertised the high output. It is better to have too much energy and turn it down than not enough. If you purchase any other one, make sure it is clearly stated it has the power (joules) as advertised. This, to date, is the best overall unit I have tested.
