These are great to have on hand and not a bad price. They're easy to store because they're so small, and that way when you need a replacement, you have it.
I ordered this to have for backup. I saw that it went on sale and chose to have one on hand. I have had my Maker for a yaer and use it weekly and don't need it yet. I do clean my blade often.
These cut very well and area great replacement blade. The only reason I gave 4 stars instead of 5 is because I think there should be some instructions on how to replace the blade and how to get them in and out of the storage area on the back of the trimmer. My first time using these and I had to google/watch a video on how to install and store them.
