About This
- 1 Dual temperature control system: one chip with two independent heating systems. When the temperature control system of one heating rod fails, the temperature control system of the other rod can continue to work, reducing the occurrence of frozen fish in the fish tank caused by damage to the heating rod, and ensuring the constant temperature of the fish tank
- 2 Heating speed is controllable: the two heating tubes have independent temperature control, and the temperature control range is: 64-93℉. The heating rod is evenly wound with 20 nickel-chromium electric heating wires, dissipating heat evenly at 360°. The heating speed and power can be controlled by individually adjusting the temperature of each rod
- 3 Easy to operate, the full immersion heater is equipped with three suction cups, which can be firmly installed in every corner of the fish tank; the outer shell can be slid away, making cleaning more convenient; the temperature can be adjusted by directly rotating the top knob; the sealed waterproof plastic can protect the internal chip. Improved durability
- 4 Accurate temperature control: There are two sets of temperature measurement systems with built-in dual temperature probes to monitor the current water temperature in real time. When the detection reaches the set temperature, it stops heating and starts heating when it is lower than the set temperature. The temperature control error can be controlled within ±1 Within ℉
- 5 Suitable for seawater and freshwater fish tanks, fighting fish tanks, turtle tanks, etc. 600W is suitable for 66-132 gallon fish tanks, and 800W is suitable for 80-220 gallon fish tanks. When installing, please completely submerge it with water and do not place it on sand and gravel

My dog loves this.
Color: Black Green, Size: 6 Inch, Color: Black Green, Size: 6 Inch
I have a large Cane Corso who could obviously shred this but, she loves it. This ball is holding up really well. We use it for outside play and she loves batting it around and swinging it from the loops.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.
