Gravity-Fed Versus Agitated Hoppers
The debate between Gravity Fed and agitated hoppers rages on as paintballers everywhere try to decide which choice will provide them with the best possible results. Here are a few key points for each style and how they compare head to head.
Gravity-Fed
A gravity fed hopper is essentially a container with paintballs in it. It sits casually on top of your gun and feeds those paintballs one at a time into the gun – or at least they are supposed to. These are generally the cheapest hopper options available and have a low rate of loading due to the speed of gravity and the bouncing of the paintballs off of each other. If you are firing too quickly, the balls in the hopper will stick to each other and form an arch over the hole, stopping the feed of paintballs. You can shake the hopper to fix the problem, but it will generally slow your rate. The basic problems with gravity fed hoppers are the reason why an agitated hopper was developed.
Agitated
These hoppers contain a motor that connects to a paddle spinning and breaking up the arches that form when the paintballs gather over the feed hole. This ensures the paintballs keep feeding into the gun at a steady pace, pushing through the hole and not slowing down your shots.
The speed difference between from a gravity operated to agitated hopper is actually non-existent. However, because there is no break in the feed of paintballs, you do not need to stop and shake them free for any reason. They will continually feed. Agitated hoppers are slightly more expensive than their gravity fed counterparts – starting at $25 and rising rapidly from there.
The agitated hopper comes in multiple different forms as well. You can find some with very simple, straight paddles that push the paintballs through the feed hole. Others will have paddles that are shaped like propellers to physically move the paintballs downward into the gun. They will not spin constantly most of the time; rather they move only when the balls stop feeding into the gun, making them more efficient. This is done with a small sensor that will detect a gap between paintballs feeding through. If the gap grows too large, the paddles will start spinning. A single 9-volt battery is usually sufficient to run an agitated feeder.
Force Fed
A force fed hopper does a little bit more than an agitated hopper by actually forcing the paintballs into the chamber from the hopper. It will usually have the paintballs fall to either side of a cone, then rotate the cone to drop the paintballs into the chamber one at a time. This kind of hopper will continually force feed paintballs for as long as necessary to keep you firing at a constant rate. These machines are highly efficient and reliable, but can cost as much as $100 for a low end model.
When making a choice between hoppers, remember what you need for your outing. If you are playing speedball, you will definitely need at least an agitated feeder to ensure constant firing – while woodsball with a few beginner friends will likely be okay with a gravity fed hopper.

How long can a mouse be left?
How long can a mouse be left if you give it one of those gravity bin feeders (which gives it an on-going supply of food) and lots and lots of water? Do you think it could be left for a week?
If you think it would be ridiculous not to see to it everyday then tell me! I’ve never owned a mouse before, which is why I am asking. I was just wondering as my friend left her snake for 2 weeks… but they only need to eat once a week.
well if I got mice I would get more than one so they wouldn’t get bored. They aren’t really the kind of animal that like handling a lot anyway.
In theory you can leave them for a week the way you have outlined, but, gravity hoppers can still be pooped and pee’d in at the bottom and also there is a risk that the Water Bottle could get blocked in some way, if you have someone just to pop in once or twice in the week or even each day (that would be my option) just to check that all is ok, also small creatures can have the habit of dying unexpectedly, so that would not be very pleasant for the remaining mouse or indeed yourself when you get home.
