I must say that I've developed a healthy respect for Romisen as a "bargain" flashlight! I only own one right now, the RC-G2 II NW. It is a simple, one mode, single AA light that puts out a solid 140 lumens in Neutral White! It replaced an old Dorcy LED light as my bedside light. Easy to use rear clicky and will blind an intruder more than long enough for what may come next. This one was around $19!
I just ordered a little 2x AAA Romisen RC-27 II Q5 with 130 lumens - just because I don't have a 2x AAA and this one also can focus from flood to throw. Not to mention this one is just under $15 shipped!
I would not reply on these lights as waterproof canoeing lights, but I would totally have them with me camping, in my car, etc. True, I have no "time proven" experience with reliability, but so far, I haven't encountered any real negative talk about Romisen lights either.
So yeah - when I ordered the RC-27, I totally eye-balled the T601 U2 and bookmarked it. Had no idea this thread existed. And now, doggone it, since reading, I am going to have to order this light - but I have to time it so it will ship and arrive on any day other than a Thursday - the wifey works at home every Thursday... lol.
Pardon the ramble, but I had to let loose some love and respect for the Romisen!
