No, I would not recommend this.

Perfect feeding station, BUT

Pros: Great for hobbist that can supervise operation

Cons: Have to monitor each feeding

Using flake, first spin after filling flake, great job, but after that little comes out without opening food door all the way.

Eheim = greatness

As always, you pay a bit more for Eheim but there will rarely be any regret. Such is the case for this item. You will need to read the directions carefully as it is a feature rich feeder with multiple settings and timing feeds available.

Good feeder

Pros: Easy to set, batteries last long

Cons: Sliding dispenser door is a hit and miss especially with flake foods

This has been working good this far ( nearly a year). I have change the batteries as of yet. The dispense slot is a hit and miss at times . I therefore set to feed multiple times per day.

It works

Pros: Reliable

Cons: I would be nice if it had a "skip next feed" button to pause for tank cleaning or special meal

I've been using this for about three months and only with small pellets. I adjusted the dispense door and I needed one in the middle so some tape across half the opening worked. It feeds every time, has a low battery indicator and the food stays dry with the little fan in it.

Doesn't last

Cons: Horrible customer service and support.

It stopped working after about 6 months. send it in to the manufacture for warranty and they gave me the run around and after 4 months of telling me they don't have parts to fix it, they didn't honor the warranty and kept my unit. Terrible customer service. very disappointing. Do no recommend.

Horrible! will not recommend.

besides the item stopping to function properly, this company has one of the worst customer services in the industry! It stopped working after a few months, I send it back to the manufacture for warranty and its been over two months and they still have no idea when I will get a replacement and when I did call to inquire about what was going on, the supposedly manager yells over the phone and hangs up! Will not recommend the product or the company. Look for a different brand that will stand behind their product.
