Product review (4 stars): It felts - which is what I wanted it to do
OK so this is basically an oversized blender. I am not sure how long it will last but for what I wanted it for the price was right and it does the job.  I bought  it to felt knitted items and for that it works pretty well. I tried the tennis balls that some user recommended - I won't use them again the are unnecessary and caused a problem with one bag when they got inside it and created a "bubble" in the side that was very difficult to work out. It takes time for things to felt in it - but I find that true in a big washing machine.  I used it in a shower stall where it didn't matter if water slops out a bit(and it does) and where there is access to hot water which I find it helps to refresh a couple of times during the process.
This was actually the second machine I purchased,t he first which came from a different vendor - arrived DOA
