Good for the price

Have owned this for about a month. out of the box the fit and finish was a tad rough in some spots but its a trainer i planned on beating it up. i scuffed the handles up with a green scrubby pad to soften them up out of the box. you should also oil this out of the box mine got pretty squeeky pretty fast. aside from that its a great flipper that does not break the bank. i have a pinned construction style trainer that i cant tighten and that drives me crazy and the extra $40.00 is well worth it for this one

well constructed
good beginner flipper
adjustable pivots
looks nice

gets dirty very easily
needs to be tightened every day depending on use
handles are pretty rough out of the box
Great for average Use, 10/10 Service!

I would have given this 3 or 4 stars as the tang pin came out in a couple days and I lost it, but I gave it 5 because when I contacted them, they sent me a new one, free of charge.
Great for every day use

Iv had this trainer for several months. I have 3 other trainers also and a few nice knives. But this thing is what goes with me most places. Took my latch off day one. And this is the only trainer that has held up to all the abuse of daily flipping. Rollovers are nice, chaplains go great, twirling is fun. But fanning can be a bit off due to the weight. Overall a great buy though!
decent overall great for the price

Great for when flipping an actual blade isn't practical or acceptable. Not gonna lie it feels cheap when you first flip it. But for the money its pretty decent. Redoing the tread locker is a must and actually wait for it to cure or it will fall right apart. Handles are a bit grip happy but you get use to it. My only concerns are the tang cups getting over worn from the lack of liners, they dent in pretty good. G10 vs metal its expected. Overall for what you get id say its well worth it. And i got the B2010R4P instead B201B4P with my order don't know why but the OR4P blade looks way better Anyways IMO so i'm not complaining.
This is well worth the money

So this was a Christmas gift from my parents, it flipped amazing right out of the box. Loctite soon after you first get it, latches are amazing, i am a young child and getting used to flipping something so large and light took a while, not long though. Also what I found weird was that I got a different shaped blade than the picture. I love it though and it looks like the alpha beast. I don't know though, I am a fetus child and I don't know that much XD
Don't take apart

This balisong is awesome, when I got it out of the box it flipped amazingly, but when I took it apart (like a dumbass) I striped most some of the screws. Eventually with enough loctite the Bali would hold together but In the end I just duct taped the handle scales together. But then I figured if I went latchless I could move the screw and pivot that holds the latch together to the safe handle it would hold together.

All together this trainer 4/5 stars if you don't take it apart. Sure the tang cups will wear out and the blade will touch the spacers but a little duct tape can fix that. Just remember, don't take apart your bear and sons balis. Oh and the pocket clip doesn't work it screws on to the scale in a particular way that it bows to far upward.
flips ok but...

I ordered the Bear Ops B-200 from Blade HQ have been very happy with it. I bought this trainer thinking it was going to be the same but the handles are different sizes and weight. The safe handle is about 35% slimmer than the bite handle and I can definitely notice it in the feel and balance when flipping. i wasn't too bothered by it at first but when I flip it for some time then go back to the B-200 it's like flipping a completely different bali when the whole point of this trainer was to be identical to it's bladed counterpart.
Best trainer thus far! (edit: but falling apart now :( )

This trainer is a lot better than CCC trainers you get from amazon. Though it is 2 to 3 times the cost of some of those, it survives a whole lot better from drops onto concrete floors and extended flipping (my CCC trainers lasted two days at most before it starts getting a lot of bladeplay/tang pin issues). Secondly, it looks a LOT more tame than some of the other trainers. I don't get a second look at work when i'm flipping this. A few drawbacks straight from the box are: 1) a bit stiff - had to oil it and flip it a while to loosen up, 2) not the best QC - tang pin is a bit marred but functional on my copy. I cant complain tho; i love this thing and have no fear of droppin' it - it's a true beater trainer.

edit: i've been flipping this a ton for the past three weeks and the G10 handles around the pivot are starting to grind away :( i can see why some steel liners can help prevent this from happening. I'll still keep flipping it but it'll be inevitable that the handles will break :( Wondering if others are experiencing the same thing?

As soon as I picked this trainer up, I could tell it was infinitely better than the crappy $15 trainer I bought off amazon. Despite a few cosmetic blemishes, this trainer is amazing. I would recommend this to anyone.

EDIT: It definitely needs some loctite, as the pivots are coming loose
