Here are the pros and cons:
Pros: Does kill off coralline algae to make it easier to remove
Acrylic safe (provided you are careful)
Fairly easy to operate
Saves time
Can reach most of those unreachable spots to remove coralline

Cons: Cost a little high
Heating area a little small for me
Can not heat in corners (just a little off) you will leave about 1/8th
of an inch of coralline in corners


Over all I found it easy to use. It takes a little time to get used to how long you need to leave it in a spot to kill off the coralline algae. After you do heat it and kill it off it does come off easier, however the scrapper (in my application) was just a little on the week side to get it. You also must be VERY careful not to scratch the Acrylic, any little piece of sand kicked up will get caught in it and scratch. So if you have a sand bed I would not recommend using it close to the sand bed unless you are very very careful. It does save time and it does get into those areas you can not get to with a traditional scrapper. My tank is 30 inches tall and the back right and left corners are almost impossible for me to reach, this product cleaned those areas for me.

I will try to get some picture posted sometime this week of the product in use.
