If i was not a owner of the BM250 skimmer i was afraid to buy it after i read this post.
don't judge the skimmer before you test it .
1. they maybe forgot to put in the pack the O ring but i believe they will send it to you (if you will decide to keep it)
2. "They use a flimsy tubing" are to reduce vibration and to keep the skimmer body from damage (you can see it also in the picture of the BK skimmer , because of that it's not good ? )
and this is also why those pump sit on the rubber .
the mesh make vibration on any pump and noise to (and i try it on some different pump ,i wish i was able to connect them to the skimmer body as it's on the BM skimmer)
3. if you decide to keep it , when you will start the pumps they will be rattle and this can be because the size of the mesh (diameter ) but when it's will be run for day or 2 that's it it will stop.
4. about those little pump i can tell you : if they was sell them separate and the hobbyist here was able to buy them maybe 50% of the ppl here was change them original pump to the Sicce pump and put them on own skimmer's .
i can't tell you what to do this is your money and if you feel bad turn it back , but i can tell you this: i am member in other forum to behind RC and i saw a lot of other review on a lot of different skimmer , there is other good skimmer in the market and i love them . but the ATI it's a great protein skimmer to and will beat a lot of good other... (i don't say that because i want to argue , i said that because i want you to know that this is a very good protein skimmer ) .
you can see here how the RD pump connect to the skimmer body , it doesn't mean the skimmer not good :
