Was really cheap, got it in a B&M sale at less than half retail price! Black & Decker is ubiquitous so parts/refills should be easy to get.
Storage is difficult as there is no cable tidy built in, so it's untidy and cumbersome to store.

Also, the cable is ludicrously short, you'll definitely need a cable extension to use it if your garden is more than 1 ft from your front door!

Often doesn't 'automatically' feed which is just a darn nuisance. (You need to feed the strimming wire out manually which defeats the object of having an 'auto' feed).
