The plastic that houses the magnet does separate on the outside portion but that's no deal breaker for me. What is, is that the clip that holds the veggies weakens over time and is no longer strong enough to hold the veggies. After a few tugs from fish the whole folded up veggie becomes a floater. You can clean the leftover veggie slim off the little teeth that hold the veggies but to no avail! They last about 6 months for me and then you need a new one.
I had two of these feeders from the same manufacturer that I bought many years ago that finally needed to be replaced. These are no where near as good. The fish pull on the seaweed and often the magnet releases and I find the outside portion on the floor. I had to stack the magnet part from one of the old feeders with the new feeder to get it to stay in place. Very disappointing.
The plastic logo was lose in the bag and so was the pad on the outside magnet. It is very hard to slide because of the material used on the interface between the magnet and the outside glass. I had to stick on a round felt piece to make it usable. For the price, it's a disappointment.
Although this -not so little- buddy has a strong magnet, the lid or better said, the paper that covers the magnet on the clip side was detached upon arrival. just hope the magnet doesn't get ruined if water gets to touch it. Hard to remove the outside magnet, it has some sort of like rubber that gets stuck pretty bad on to the glass.
I have one of the old models with the magnet covered with felt that slides just wonderfully and has lasted 4 years. No problems. The new model that I have had for 8 months still works, but it doesn't slide. The advantage of the older model is you do not have to stick you hands in the tank to secure the clip. Why did they change the design? Why did the ruin a good thing? How can they say the newer model isn't supposed to slide? That was the big advantage of this clip.
From the product description, one is led to believe that the clip may be used to place food items to whatever depth wanted on the tank wall without need to get ones hand or arm in the tank water. That is misleading. To set the clip on the tank wall your fingers must go into the water to whatever depth you want the clip on the tank wall. Only if you place the clip at the surface would staying dry be possible. I was trying to feed snails and crabs, and needed the food held near the bottom of the tank. The clip, and therefore the food in it, floats like a cork, so you have to hold the clip down in the water and bring the outside magnet and the clip together through the tank wall where you want the food presented, because once connected, you cannot slide the outside magnet at all. Do NOT expect to slide the magnet on the outside tank wall to position the clip on the inside wall where you want it. It is designed to prevent you from doing that. You might tear off the liner on the outside magnet and get it to slide, but as provided, it is NOT going to slide. It sticks like glue. You literally, with some difficulty, have to pry off the outside magnet to get it loose so you can move it, and when you do the clip pops to the surface. Why in the world didn't they make it work like a magnetic algae cleaner so it could be moved where you want it? It sticks and stays where you put it very well, but you cannot slide it at all. I was very disappointed.
