Needs some DIY adjustments.

Really cute but so bright, it becomes the centerpiece of your living space. My hamster never touched the wheel, she preferred metal ones, and just chewed this one up. She also spent hours chewing the bars. She loved the little condo. It's quite a high drop though and hamsters are pretty blind so you might want to put up little walls on the platforms. Also, I put cardboard down on the platforms so her little feet didn't fall through.

Works good but you'll need to adjust the tension screws for stability.  Further, the thread is a bit course, resulting in slop on the adjustment.  It can't be removed, if you need a more precise piece of equipment, get something else.

Worked well, but some modification is required if running a 6 1/2" round speaker, but very minor.  the 5 tabs (3 small, 2 big), on the inside of the circle need to be removed.

Bought these to replace the one missing on my car.  They do not fit without adjustments.  Had to do some cutting and trimming off the back.  Ultimately getting this to fit but had to use a couple of twist ties to hold them in.  It works and stays put.  It's  definitely better than not having one at all but I took two stars away because they require the adjustments.

I have not hooked up the system yet so I may have to update this review. The reason I am writing this is because of the stupid people who can't figure out how to drill the 2 holes bigger in the mounting bracket. Make the holes bigger by some method, drill, Dremel and move the screw head down away from the bend. Duh! Hell you could probably just use a bevel head screw.

The finished product looks good, but I did need to make modifications in order for the glass doors to fit. They were 1/8inch too tall.  Absolutely no way they were going to fit otherwise. The pieces in the back of the unit did not match up very well, but it was behind the unit so I didn't care so much. One of the holes for a piece did not line up at all so I didn't install that part as it wasn't critical. I would overlook these details because of the price and the end result looks good.

Worked like a dream. Had to make small adjustments to fit in place, but I figured I would be having to do that before I even purchased it.

Didn't fit Like it was suppose to. Had to modify it to get it to work.

Needed slight modification to fit. The rubber boots make it sit too high, and the intakeand outtake hose port extends too far to properly connect with unmodified hose, causing a kink in the hoses.

I bought these hoping that they would fit correctly without adjustment.
They ended up needing a bunch of cutting to make them fit.

O well, they work.

Required some modifications and fabrication to make it work.  Wish a us standard lock maker would make this design.  Does not fit a US standard door holes.  I used a combination of door knobs and US works on the inside.
