Absolutely brilliant speakers for the size and cost. They pop up and squeeze down to save space and can link together for extra volume.
I would recommend picking up a cheap aux extension cable though if linking then as the cable plug into your device is quite short. This does mean though that it tucks away nicely underneath the speaker though.
Excellent little converter, works like a dream. This is my second purchase as I broke my first due to lack of care, but that's not to say it's a flimsy product. For a cassette the sound comes through very well with no noticeable loss of clarity. The price is highly reasonable for the use it gets and for the quality I would not feel ripped off if I had paid 4 or perhaps 5 times the price that I did.
Delivery was prompt and packaging was sound. Just a pity I can no longer use it as I just wrote off my car...
