    Strengths:    Sleek, technological, designed well, works fine for now, pumps fast.

    Weaknesses:    Weak plastic parts makes it impossible to use it as floor pump. Jumping pressure values on digital display. Sound is weak. Valve is way too hard.

    Bottom Line:   
    In fact I bought this thing just for the case, when my old one failed and I needed one urgently. First I pumped the front tube, quite surprised that the default preset was set for 120 Psi (don't even think to rely upon these defaults). Digits were jumping crazy, showing pressure values variating in the range of 10-15 Psi up/down. Might be, this meter is too sensitive for reality?
    Well, the leg broke after 3 times usage as the floor pump (it is made of plastic). The second attempt to pump rear tube caused its nippel to crack. Thankfully, I have had a spare one. Don't really know, might be the defective nippel, but it was great with older pump.
    And, yes, like Leonid said, I was damn surprised, there's no access to the battery. If this one will run out after a year, I'll need another one? How high can be the value for such a gadget?

    Strengths:    It looks so cool that all of your friend will envy you.
    It did work for a while.

    Weaknesses:    The speaker signal volume is surprisingly low even when I’m at home.
    The gauge electronics block is not serviceable. When the battery ran (CR 2032) low, indications became 20-30 psi higher. Luckily, I realized it before I blasted any of my tires.

    Bottom Line:   
    Sigma Sport Lambda Jet Analog had served me well for a year although it was a bit hard to check the analog gauge unless the sun was really shining. It kind of killed the idea of having a pressure gauge. What’s the sense in carrying around a heavy pump with a manometer if you can’t see its indications because if its size and weather?

    When I saw a digital version that could signal once the pressure reaches the set level I sure grabbed it. The production date was around 2002 but I didn’t think it would tell adversely. Guess what? They put a Lithium 3V battery inside and glued the box. It took a year of life at stock and month of cold weather for this battery to die.

    Had to break the digital gauge box and replace the battery. That wasn’t easy: when you take out the 4 screws you will find that the cover of the box is safely glued on perimeter. I had to actually use small pliers to open it. Not sure if I can do is again because the box got seriously injured doing the surgery. I used some clear adhesive tape to "seal" it back.

    I would recommend this pump to anyone who doesn't mind getting a new pump every time a built-in battery runs low.

    Strengths:    a smidge bigger and heavier than a minipump, but with the ease of use of a floor model. appears well made and durable. valve works well and is quickly off/on. alot of pump for the price. looks really trick, works even better.

    Weaknesses:    a bit geeky, but, hey so is alot of james bonds stuff!!
    hose could be just a bit longer(but i wouldnt want this if it meant added length. pressure alarm could easily be louder

    Bottom Line:   
    ive been thru pumps and can say i have found it!!!
    this thing is an engineering masterpeice which actually works. good compromise between weight and function. moves air but of course the limited stroke means youll pump longer to reach pressure, but its fun because its basically a floor pump and the gauge/alarm (which is easy to see)spurs you on. this thing is brilliant - buy it, unless you need the absolute lightest mini. but keep in mind most minis are just miserable crap which sell cause they feel so light in the showroom . . . this thing semms like it will never work in the showroom, but after you actually use it you are convinced. this is THE pump!!!!!!!!!!!!!!
