Product review (5 stars): VERY CONVENIENT
This device is very convenient and has saved me a lot of time and trips. I can now do laundry in my apartment without going to my over-crowded laundromat in the rain.

PROS:

Very convenient
Efficient
Large load compared to other portable devices
Lightweight for a washing machine

CONS:

There's this odd hole on the washer side near the top. Sometimes the sloshing water gets in. Doesn't seem to do anything, just appears more concerning and out-of-place.
Doesn't handle old shirts very well. I've had it rip a few of my older t-shirts, especially around the collar and the bottom edges.
The lint catches isn't very effective. It does catch lint, but only a small percentage. The rest still dry-up and stick to the clothes. I do multiple rinses to get them out and would just take more time.
The rinse cycle is confusing. You can add water to the spin dryer, but based on how it spins it seems like the clothes barely take on the water. Rinsing with the washer seems to require multiple rinse cycles for the clothes to appear relatively ready for the drying.
I don't get what the "Wash" option is for the water pump. Doesn't seem to do anything.

Despite the minor cons the convenience of this device outweighs them.
