Disappointed due to Led light was not working at all.Without light it doesn't looks good

It works well out of the box but you may not be able to use it in an outside pond unless you have a pre-filter on your pump otherwise you'll be cleaning it constantly. It is a little fragile - you will want to make sure that you have a nice flat surface or it will bend some once heated in the sun. Also make sure that your pump is rated high enough for the flow. Or maybe you need to use a smaller hose from the 1 1/4 fitting that comes with.
The stream can separate and trickle down the face of your waterfall wall (so make sure that the liner is behind the wall or sealed good also when the wind blows it can blow the water out of the pond due to the thin stream so keep that in mind when designing your waterfall and pond. You don't want your pond to drain and burn up your pump. Maybe I should have contacted support as well to get some advice. Over all - eh. for the high price it really can be a pain. This is the second one I bought and the first one only lasted a season. If this one only lasts a season I won't buy another.
It may say not to use in out door ponds on the box this year not sure about the first box last year - but the pics make it look like it is for outdoor use.
When it works - it looks nice.

Love, love, love this waterfall. This was a great addition to my pool.

Amazing waterfall. Really made my pond. Product description says it's not intended for a pond, but if yours is pretty clear with no gunk or debri floating around, should be fine. I also ordered the little brush to clear out debri, which was helpful off the bat, since the tub I connected had a decaying lily pad leaf in it and caught inside the fountain obstructing water flow. So, took the cap stone off the waterfall, and since it's clear, I could see the issue immediately. The leaf was cleared quickly and immediately. What an amazing and calming effect the blue light has. I did the pond myself, and this product took it from pretty nice to DANG! Guests at our home just stare at the pond agape with awe and admiration. Made me look like a pro! I'm guessing for the $170 I spent for 2 each, I just boosted my home's resale value by $5K. LOL. Also, using the Tetrapond water garden pump 1000 gph and works fine (using 1" corrugated pond tubing); pumps adequate flow to make the water fall in a nice "sheet" form.

One thing to note; I am not super technically savvy. I am learning as I go and read a lot of reviews to help direct and guide me. Since I was using this for a pond application, I had to buy a 1-1/4" male thread with 1" hose barb to connect my hose from my pond pump. For the lay person, this can all be very frustrating to get an awesome product in the mail and have no idea how to hook it up. I had to google for this little piece. Would be nice if these little things were more articulated in the description I guess or could be found among the suggested product pairing.

This product was a complement to our pool renovation project. It is simplistic and our stone mason was able to incorporate it into our water feature. I would have given it 5 stars if it were more reasonably priced.
