Excellent advice SHIFT

EDIT - 30/03/2015 - The distributor sent me a replacement pack for products damaged during transport priori, I have not yet tested the replacement products for lack of time (received at the time) but the delivery was very fast, and very courteous, so I change my rating, especially since all the products I have already been operating for the purchase without having to recharge the batteries. I recommend, because with some vendors in the customer service was much more complicated than that. Service in French stock in Europe priori Germany, so no worries with products shipped from HK ... and customs fees, duration of 3 to 4 weeks here ... the advantage is to have almost the same prices, but worries less. Congratulations.

Hello, the product bought because I rechargeable battery life of worries about another similar product in AAA with 10 LED ... short 2-4j batteries with a set of batteries, so I bought it product indicating 50h with AA batteries, lighting is less powerful (1 LEd against 10) but very correct, by cons we must place more and better detection if product not placed on the ground ... to climb stairs all lights carefree, to go down it lights up at the last moment because the sensors are on the ground ... but that's okay.

By cons I have a concern, having ordered 3 sets of 3 to test (9 in all), the first batch no worries, all the lights work, the second lot, unfortunately 2 lamps 3 are failing ... they s 'light well when you put the batteries, but the motion detector appears to fail after 30 seconds after insertion of standby batteries, and no ignition, removed the batteries are recovering, 30 seconds and again after more than average on again without removing the batteries ... so Syur 6 products tested 4 work perfectly, HS 2 (the same batch).

I have not yet tested the 3rd set of 3, the batteries are being charged, but in the first 6 2 are a priori HS ... I expect to open the third pack of 3 I put Battery charging, then I will contact retailers optionally, depending on the quantity of products operating in the third set.

EDIT: 03.25.2015 - it is confirmed, 2 of the 3 products of HS cardboard (SN 0A6ONH5I), both having the same serial number, and a third product of another cardboard (having bought 3 of 3 or 9 products) ... and of course the 9 2 defective, and a third that has successfully run after a difficult start (same symptom as the first two), but playing with the sensor, pressing a little above, I managed to get it started ... the other 2 are lit by inserting the batteries, but after being turned off at the end of ~ 30 seconds never rekindle ... as if the detector not working. So, thank you to tell me the procedure for exchanging defective products 2, hoping the third will continue to operate. Otherwise practical product, I guess I came across a set of 2 with a series of default (by the way all my 9 copies have the same serial number). Thank you for giving me the procedure, because Amazon automatically offer me a refund but I must not return 2 but the 3 products, including the one that works, and I would still order 2-5 packs of 3 put elsewhere.
