Xiaoyztan Aquarium Heater Guard Protector 17 Inch Detachable Design Black Plastic Cover with Suction Cups Heat Resistant Fish Tank Heater Sleeve for Water Heating Rod Safety

I wanted a non-glass heater, but prices for 150 gal were crazy. Eheim 3619090 Jager was affordable, terrific reviews and a THREE YEAR factory warranty!!! So I added this sleeve to protect it. Wish it wasn't so tight. Pushing it on caused the suction cups to scoot off - took many tries. It's now on and works like a champ!

Good protection. Used for eheim 250W heater. A little snug but fit good. Does what it should...protect

I love the product

I bought this heater guard around a year ago because my turtle kept breaking her heaters- she entertains herself by knocking the heater into the glass of her tank over and over again.I'm currently using an eheim 250 watt heater and this guard fits it perfectly. I remember it was a bit tricky to get it on the heater though because of the very snug fit, but it *will* fit if you patiently wiggle it on for several minutes.So far, so good. The heater hasn't succumbed to my turtle's assaults and I've had no problems with this guard. Will update if or when the heater guard breaks down.

It's perfect for the Marineland 300W heater. The sections are different lengths and can be added/removed as necessary to accommodate your heater.Edit: a year or so later and this thing is still holding strong. Been relocated and moved around several times and the cups are still strong.

Good product keeps my pond at right temp. In my experience you just have to adjust its temp by a thermometer the number settings on top don't seem to be accurate but works once you figure that bit out.

Works great for the aquariums

Fits my fluval m300 without the top part. I had to raise the temp on the heater control to 83 degrees in order to get my water to 77-78
