Modes of Operation

Standard Dispensing: Knob A – Open, Knob B – Closed
In this mode, the dispenser dispenses the liquid normally into the receiver from the bottle it is mounted on.

Purging: Knob A – Closed, Knob B – Closed
In this mode, the liquid is re-circulated into the same bottle on which the dispenser is mounted. This process removes the air from the dispenser, without wasting any reagent.

Dilution/Rinsing/Second Liquid Dispensing: Knob A – Open, Knob B – Open
In this mode, the liquid from a second source can be dispensed into the receiver. The second liquid can be distilled water, thus allowing the user to rinse the instrument without dismounting it or dilute the reagent within the receiver.

Bottle Refilling: Knob A – Closed, Knob B – Open
In this mode, the liquid from a second source can be used to refill the bottle, without dismounting the dispenser.

Last a while. Will be buying more toys soon.
Color: Consuela the Cactus - Large, Size: Large Dog
Best dog toy I have ever bought. I have three dogs, two at the time I bought this toy. It took them over a year to break through the first layer. The flower comes off first so be careful your dog doesn't swallow it. It still has the second layer so it still looks like a cactus. No stuffing to clean up when they tear into it, which makes it far less messy than other toys. One of my dogs is obsessed with fetch so I use it like a ball inside. The oval shape makes it hard to ensure when it bounces that it will bounce straight. It's bounced into walls and other stuff that I wasn't intending it to hit. Not much of a squeak so I can let them play with it for hours and I don't get annoyed with the noise. Great toy that lasts a while.

Nice Value
Color: Consuela the Cactus - Large, Size: Large Dog
Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!

Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.
