Expensive with poor kill rate
on June 21, 2011
Purchased in early June 2011 when there were no Amazon reviews.
Treated 31 dandelion weeds on June 12th, being very careful to use the zap as instructed. Even though the wand is long you have to bend over to examine each weed as you must attempt to locate the true center - your goal is to hit the root-head dead-on. Not so easy. I chose to leave the heat on each weed for ten seconds, instead of the recommended eight, just to be sure. Over all, a very slow process.
After one week, on June 19, only three weeds appear to be dead. All the other weeds show signs of being injured, but definitely not enough to kill them (there's still an average 80% green leaves on the weeds that survived treatment). Total percentage of successful kill: about 10%.
I also found the on-off toggle switch to be in the most problematic place: right where you apply hand pressure to the zap wand to hold it on a weed. I accidentally turned it off, and discovered the problem about weed #3. I then had to slide my hand down the handle to avoid pressing the toggle, which made my finger hit the finger stop, which began to hurt after only a few weeds. Poor design.
On the plus side, the instructions for use are located right on the zap wand housing, which is very convenient. In all fairness, too, it did kill a couple weeds completely.
For a yard that is already low on weeds, you might make good use of the Nature Zap. If your yard is over-run by weeds, though, the zap is like a painfully slow electrolysis device. And at that, with such a low kill rate, you have to factor in repeating treatment in hopes of killing the target weeds.
Finally, I can't image there is not a less expensive way to apply a hot poker to a weed (just a heated spear is all it is. No electric current to the weed; just heat). At $89 I just feel this was nowhere near a good buy.
