Query: Huge Disappointment

In a world of 18 and 24 volt rechargeables, I was hugely disappointed in this product. I bought it this spring to replace my manual sheep shears I'd used for 20 years, hoping to be able to reach those tight spots I can't reach with my string trimmer more quickly.It binds on almost anything, can't handle the occasional tall fescue flower stalk, and if I'm really careful with my trimming, I can get almost 10 minutes of real use out of the battery, which is less than half what the product description claims. Although it's a really cool looking trimmer, I think I'll buy a new pair of sheep shears.
