I just spent 1 hour putting it on, took a ride, and spent another hour taking it off. Unacceptable noise from the alignment even without hitting potholes. Fortunately, it was a gift.

It has some creaks as if it resonates at certain RPMs, that's where you feel it vibrating.. otherwise it's just fine.
It has taken in a lot of water but has never leaked.
(If the sun sees the plastics for a long time, they might yellow.)

2 stars. It lasted about 3 years. In the last week, the thin plastic that holds the lid upright when you open the suitcase broke. Also, after a strong jolt with an empty suitcase, the plastic that holds the suitcase to the base broke, causing it to fall onto the road while in motion; fortunately, I didn't have anyone behind me... In the end, I managed to tie it up just enough to get home.

A simple suitcase to do your everyday job. It's nothing special. The only negative thing I can attribute to it is the noise it makes when passing through rough asphalt. It's incredibly annoying and unbearable. Now, as for the rain, I can't give an opinion because it has never been tested in water.

I have had the suitcase since 2012.
It has not leaked a drop of water in heavy rain, nor has it shown any signs of struggling even though I often exceed the manufacturer's weight limit of 3 kilograms.
Once the lock got a little stuck, but with a little spray it became like new.
After many abrupt openings that I have done for years on a daily basis, the plastic hinge that connects the top and bottom parts broke. I have left it like that, and I still don't have any problem. Only the capacity is not enough for me. Otherwise, I recommend it due to its price.

It is incredibly fake and not worth even its money. I believe it should cost around 10€ at most 15€ and not more. Its lock broke very easily and cannot be easily repaired. Choose something else. It is worse than the cheapest Chinese products of this type. Its plastics are very soft and break very easily. Its base moves easily because it cannot easily tighten on the motorcycle or scooter rack. Completely fake.

Update 2020! It is quite good for the money it costs. No issues in the 5 years I have had it on my motorcycle. Economical, with a relatively satisfactory space, and hard plastic material. No problems so far! It has not even taken in water from the rain! Also, with a little extra money, you can install a backrest, which is very useful for the passenger. It is perfect for small scooters and mopeds! However, it lost one star because the lock broke easily when I fell, but someone can replace it relatively inexpensively so as not to buy a new trunk again.

Terrible black, I have used the SH 33 twice on my scooter and with the first rain it has turned into an aquarium far away!!!!!!
