Bought 2 of these to test them out since I have 4 tiger shark in service, good thing I only bought 2 for the test. if you had used their previous stainless blade before, and you liked it, then dont waste your money on these ones. the blade is not even close to the sharpness of the previous blade, and it certainly did not scrape it clean like the old one. tried it for 2 weeks now, and it is getting worse on the scraping job.

this is a good design & idea, but they need to sharpen their blades, as well, these blades can't not be changed out like the old ones, so you have to buy new attachment once its busted.
