Review (4/5): The unit is pretty flimsy plastic so it needs to be babied
The unit is pretty flimsy plastic so it needs to be babied. It's louder than a gas-powered weed eater so you're probably not going to use it if anybody in your zip code is likely to be sleeping. However, it works as advertised. Fortunately another review here on Amazon pointed out that you have to poke out the red clip at the very bottom of the handle in order to get the cover off to put the batteries in. No instructions came with the unit. I didn't drop this to 3 stars because of the price. The most important thing is functionality and it does pretty well in that department. As long as you're not using it to prop open the front door it's not a bad product for the price.
