The lasers themselves are robust and solidly constructed with a nice finish to boot, the laser is strong but not too strong, the torch itself is strong enough to get cats to track it. My two have greatly enjoyed the return of The Dot to their lives after their old pointer died.
Surprisingly however, both my cats enjoy the small mouse which arrived with the lasers even more than the lasers themselves, both having grown rather fond of it. They enjoy carrying it around, chasing it, sleeping with it. I just wish it didn't get lost so easily.
