I have to say, I've used and used this little tiller, and it's just come through for me every time. It's battery operated, and I have to remember to charge the battery up, but other then that, it's a breeze to use. I love that it's not heavy, I can lift it easily and I can use it easily. It digs and digs and digs.
We still have the big tiller that John operates, but I can't manage it. I feel like I've been beat up every time I try to operate it. This one is just perfect for me, so if you need a small tiller (4 tines), I highly recommend it.
