Hi,
Hoping for advice/reviews and wonder if anyone has experience of using Lister Laser 2 clippers?  I normally get my 3 ewes sheared by a local farmer but thinking about doing it myself this year.  I've seen these advertised and noticed that you can use the Lister Wizard No 13 blade for shearing sheep using the horse clipper head.  Has anyone else successfully used these as this would solve two problems in one stroke if they are capable of doing sheep and horses.  Otherwise I would have to buy the sheep head which is interchangeable with the horse clipper head.  Thanks in advance for any advice/views.
