We had a problem with the first set (they tend to overheat fast) and they sent us a replacement promptly! The second set was great! Just make sure you take breaks between sheep you are shearing because they will start to shake and become loud. We like them for the price and for how well they cut the wool. Be very careful with these shears though, because they WILL cut the sheep's skin- even though they say there is a guard that prevents this. Be particularly careful under the sheep's legs in their armpits-that's where the skin is thinnest and where these clippers will cut.
Otherwise, we like the clippers-Oh and one more thing-these clippers are very heavy! Your arms will tire quickly!
My husband says this is the best item I've ever ordered from eBay!
We have a large dog with a thick undercoat (who is older, which makes standing on a grooming table very difficult).
While we may not have given her the prettiest grooming job... the shears did the job!
My husband was so impressed with the quality of these shears (and carrying case!).
