Orb has better sound than the dot and hue bulbs can be set to last state yes
what are these like over the amazon 4th gen dot? is it just down to sound quality? do these have better mics to pick you up. also is the bulbs better than the TP link bulbs as i find if we have a power cut they go back on do these remember the last state ?
See these deals get downvoted a lot since they changed to orb shape, people always mix the echo and dot up.
That's a different device (the dot is much smaller than this one)
Only dots are around that price.
