I have a valley oak wheel hoe I have had for over 10 years and that I love. Like the Glaser you can turn the handles so you don't walk in the rows and it works quite well.

I've used the Glaser off and on for years. It does work well but has a hard time on larger weeds and in clumpy soil.

The offset is a little awkward to get used to and you don't have nearly the same force as walking behind it, but like I said, for small weeds and finely tilled soil, it works well.
