  4. Great product! just one little detail... 4 Star Review

    The lightning thinner does cut off more hair than regular thinners! I like the length and the way it handles. The only thing I did not like was I could not adjust the blade tension myself (there is no adjustment knob), that's why the four stars.

    [EDIT: Tension on internal assembly shears such as the Lightning™ are adjusted by using the UFO key on the underside of the screw.]

    I absolutely love the straights and thinners! They cut like a dream. They don't quite fit my hands, but they cut is so nice it's worth it!

  6. Wow! 5 Star Review

    Posted by on 7th Jun 2016

    The first time I picked them up, I thought they were too light. They weren't heavy enough to be real. Now that I've used them for a couple of weeks, I'm in love! They cut through coats from Cocker hair to Poodles. They are whisper quiet, too. I have used the tinning shears to do almost an entire hair cut with beautiful results. My one complaint would be that this is the only set of shears I have ever bought that did not come with a cleaning cloth. Kenchii, be a dear and put a cleaning cloth in this set so I can keep them clean and looking new!

  7. Best Thinners Ever! 5 Star Review

    Posted by on 10th Feb 2016

    I just bought these at groom expo west, best decision I've made in a long time... you really do get what you pay for. I've had tons of different shears over the years and was always a geib girl, but these blow them out of the water. The lightning thinners blend everything perfectly and give you a natural soft finish!
