Just bunkers at fields:
- Extreme Rage
- Plywood contraptions
Extremely small size
Not designed for paintball
I picked up a couple of these bunkers to work on my stance. I figured pointing a camera at the bunker (with it setup in my living room) would help me work on playing tighter.
I got two bunkers for $5.50 ($2.50 for a can, $3 for a "castle"), and spent another $8 for a manual air pump.
I knew they were going to be small, but I didn't fully appreciate how small. The can comes up to about mid chest on me, but it's only about 2" wider than my shoulders. The tall parts of the "castle" come up to about crotch level (and I have short legs), with the middle not even coming up to the top of my knees. For reference, I'm only five foot, five (and a half) inches. Bigger guys aren't going to be able to fit behind these at all. Since these are so much smaller than regular field bunkers, they are almost useless for my purposes.
Out of the two bunkers I bought, one had a small leak. Over the course of 3 days, the can lost about 50% of the air I put into it. After 8 hours, it had a noticable tilt. By the end of a day, there wasn't enough air in it for it to stand up. And this is a new, never shot, bunker. There are no obvious tears, and the fill ports were plugged correctly.
These bunkers are not actually designed for paintball, they are designed for the Battle M.A.X. "shooter tag" game. It's basically low-velocity paintball for kids who are too young to play actual paintball. If you are thinking about buying these bunkers for use with actual paintball guns, you will end up shooting holes in them.
To me, the only good thing I can say about my experience with these bunkers is that the mistake of buying them only cost me of $14.
If you're looking for bunkers to practice with or to actually play with, look elsewhere. If you are looking for a way that your YOUNG children can pretend to play paintball, the Battle M.A.X. system might not be a bad idea. I would not recommend this for people over four feet tall though, and be ready to deal with leaks..
