I only have this and the alien defender, but alien conquest is already amazing. In this set, you don't actually get any ADU (alien defense unit) soldiers or vehicles, but the tripod more than makes up for that.

Pros: Great minifigs, first of all. The lawyer (that's what I assume he is) has a great scared face for when the alien thing latches onto him and for when he's running from the giant alien war machine right behind him, but also a good calm face for before the attack or after he's rescued. The alien is better than the little hunchback one from the alien defender, although his blaster is neat, it wasn't really needed in this set, as it's hard to fit in the cockpit. There's also that littler alien that can latch onto the lawyer. The tripod itself is a work of magic, with 3 guys and one that can basically aim anywhere on the ground to shoot any person that stands in its way! It has a pod in the back to hold the lawyer in and stands pretty tall. Great for display.

Cons: Not many, although for 20 bucks they could have included a small craft for an ADU soldier. You can fix this by getting the Alien Defender alongside this set, but then the poor soldier is pretty outgunned. While the alien latching onto the Lawyer is cool, you have to remove his hair to do so.

As you can see, this set is very very worth getting, with only a couple cons.

5 out of 5!

This 10 dollar set is a bit small, but looks very good when completed.

Pros: Both the buggy and the alien ship are good, although the buggy is obviously the star of the set. The little ship can actually fight fairly against the buggy since it has 2 guns and the driver (who looks awesome) carries his own weapon. The buggy is very well done, equipped with two missiles and two laser guns that can be angled to shoot down alien ships, or put in the drivers hands. The driver is gonna have a hard time seeing over that front part, but it's got some neat detail. The buggy also comes with two little pistols as what i assume are exhaust pipes.

Cons: It's really more of a 7-8 dollar set but just a couple extra bucks isn't bad.

If you wanna check out the Alien Conquest theme, this is definitely the set the start with. I'm gonna get the tripod next.

This set is a pretty good introduction to Ninjago, with some great figures and an awesome bike.

Pros: both the ninja and skeleton have weapons

The golden nunchuck is SWEET

The chopper is pretty large and has some sweet flames going on in the back

The back tire of the chopper is very realistic and powerful
The hammer function of the skull works well

Cons: The bike falls over sometimes, due to having a very small front tire

this set, other than one con, is really good!

For this amazing little set, I'll just do a simple pro/con list

Pros: The dump truck has great tires, and is all-around a speedy little vehicle. The dumping function works really well, and the back fits lotso perfectly. The mini figs you get here are great, the little orange guy has his changing face and somehow looks intimidating, and lotso and the octopus are neat also.

Cons: this set looks like a 15 dollar or even lower set, but it's 20 for some odd reason. Also there is no where to keep the octopus.

Still 5/5 because it's such a great addition to any collection!

This is easily my favorite space police set. The color scheme is very similar to blacktron, which is my favorite theme, so the ship looks very nice and sleek. Brick daddy and jawson are excellent figures and look like true space thugs. The hidden missile is incredible, unfortunately it is so well hidden that you can often shoot yourself.

On the downside, the commando was sorta pointless. His oxygen tanks won't be acting as a jetpack anytime soon, so he'd be slaughtered in 3 seconds. I know people on this sit complain about the secondary ships, but they're better then a defenseless human. I thought we wanted the humans to win!

5/5 for the awesome ship and figures
