I like mine because it is simply a quicker process with minimal fuss and I'm back to listening right away.
The negatives? The solution pump on the top arm doesn't always work well - I get a couple drops on the top when the bottom is well covered if I haven't used it for awhile. I compensate with a quick squirt from a bottle of solution on the top when this happens. Also, the scrubbing strips are not the simplest thing in the world to change out.
Bottom line, if you want a quick, simple solution, the nitty gritty rocks. If you are obsessed with super clean records and are willing to put in the extra time and effort to get them, there are other options that might suit you better.
