Review (2/5): This is a good product but the problem for me is also hard ...
This is a good product but the problem for me is also hard to find the replaceable head. I am not sure the heads for DL80 or DL90 would fit this one. And even if they are fit, it is also cost you at least $15 to get a new head. I don't think it is valuable to invest ur money in this version.
