    Ratchet is smooth; leverage is very good; switch is not sloppy and stays put. Easy to put bit on. Easy to remove bit

    Have the zyklop 1/4 and needed a new 3/8 inch…. Thought I’d try this unit. Great grip and form factor. Feels great and balanced in hand.

    Great Ratchet for the money. Nicely weighted. Feels good in the hand. Switch requires just enough force. Looks like it will last a long time

    Great ratchet

    Feels good in the hand and operates well. Small motions in confined spaces does not totally limit this ratchet's motions. Only complaint is that the switch is a little difficult to move (maybe because it hasn't worn in).

    Awesome Ratchet

    This ratchet was definitely a nice upgrade from my basic dewalt set.

    Great to use!

    I use this in the field and it’s great for working in tight spaces with the number of teeth it has. Ergonomic handle is great too.

    Well built and tight tolerance

    This ratchet is phenomenal. Well built and it has heft to it. Long enough to get some real leverage on stuck nuts. The gear is tight and allows for operation in some tight spots.

    Really nice ratchet. I would have given it 5 stars but it doesn't appear this ratchet is able to be rebuilt.

    Finally a Good Rachet

    I upgraded my 30 year old craftsman ratchets. I love the Wera. Nice feel, nice heft, and the Wera logo in the details.
