"First of all, let me remind everyone just as the package says- these clippers are for light duty use. These are not professional clippers, however I believe I achieved very good results with my two dogs that are westie/pomeranian mixes. One has pom hair and the other has westie hair, both were very long and were definitely in need of a clip. For my dog with the westie hair, it cut through it like a hot knife through butter. The one with pom hair is very thick and course, but it still cut through without any discomfort to my dog. The clippers did get very hot after about 20 minutes of use, so I unplugged them and let them cool down before resuming, once again, these are not professional grade clippers, so that is to be expected. After fully trimming the first dog, the clippers did need adjustment as the were chattering real bad. Adjustment is very easy with a standard screwdriver. Overall, I think this was a very good purchase, I trimmed both dogs for less than the price of one professional grooming. I had no problems with the guides bending as one review stated, and yes, they do clog occasionally, but I would just tap them out on the table, and it wasn't an issue. Overall, for the money these worked better than expected, just remember, if you or your dog start getting frustrated with the process, just stop and take a break."
