    Involvement Level: Expert (understands the inner workings)

    Pros: I bought this LiPo battery for my Blade 450 RC BNF helicopter that I have owned for a couple of months now. I already had two e-flite brand LiPo batteries when this was delivered, so I can stay out at the field longer now with 3 batteries.
    Unlike ZdenekJi reported, I do not find any significant increase in flight durations with this battery. From a full charge level (~12.4 V) it discharges in flight down to 60% cell voltage (~11.3 V, I think) using the same 6 minutes on my transmitter timer that my e-flite batteries do.
    That said, I am pleased with the price (< half of an e-flite battery) and the build quality. So to summarize:
    - flight durations equal to (but never exceeds) my other batteries
    - looks nice in the air (orange - oooohh)
    - best price I've found yet
    - reliable and fast delivery
    - good build quality
    - all wires are sufficiently long for my Blade 450

    Cons: First, I noticed that this battery is warmer after a flight than my other batteries. Charging the battery goes fine with no issues. Also, this isn't much of a con, this battery comes with dean connectors so I had to buy and solder on the e-flite EC3 connectors to fit my Blade 450 (not a big deal; there are lots of videos on the web - check the Horizon Hobby website).
    Lastly, I haven't weighed this LiPo but it feels slightly heavier than my e-flite batteries.
    - battery gets warm during flight
    - may need to buy and solder your appropriate connector as it comes with deans
    - slightly heavier than my e-flite batteries

    Other: I would recommend this battery to anyone looking for a good value in a second (or third, or fourth...) LiPo battery for their 450 size RC helicopter. But don't order this battery because you think the flight times will be significantly longer (because for me they were not). Order it because it is a cost-effective, quality LiPo battery.

    Involvement Level: Expert (understands the inner workings)

    Pros: This battery has everything you would expect: Heat-shrink tube around it, silicone-insulated wires including the charging ones, compatible charging connector with my E-flite chargers. This battery is only rated 15C, but it doesn't matter since it has higher capacity than the originals in its place giving sufficient permissible current. This battery gave me an additional time boost. I wasn't yet able to measure the exact total time, but from my voltage measurements, I dare publish this estimation: Original "1800mAh": 6:30 Other "2200mAh": 10:00 This battery: 12:00+ (extrapolated from half discharge). I just soldered a connector appropriate for my helicopter (EC3 female) and glued a loops-side of a Velcro to its side. The battery fits well in my Blade 400.

    Cons: I was disappointed at first to find out that the thickness is not the same as with the rest of my batteries. It is about 3mm (1/8") thicker. Luckily, there was enough space under the canopy. Another potential problem is the weight - this one is about 30% heavier than other batteries for this model. It surely contains more metal per unit of volume as the weight is much more than justifiable by the size increase. Anyway, the classes of models this is intended for are strong enough for crazier loads than overweight batteries - think "bags of oranges" or "caught fish" (on Youtube). Just saying in case you were a gram hunter.

    Other: Double the flight time for only quarter the price of a regular battery.
