The casing is rugged and well built, so should last for years, the many effects are nicely varied and in automatic mode the repeat rate is long enough for even the longest tracks.
The laser output is bright and well focussed and with a little fog they are enhanced.
Sound mode is affected below S6 Level by the noisy fan which causes spurious triggering, The sound levels range from S0 which is the sound Off Mode, S1 is the least sensitive mode which is brilliant for very loud bass pick up down to S9 the most sensitive.
Multiple Safety labelling and leaflet are good, although the use of the safety interlock socket and plug provided usage would be better if the safety aspect sometimes missing on cheaper lasers was emphasised
The manual is adequate and might be a bit basic for those who haven't used this type of product before.
