The Ecolife ELAN side case for the Nokia Lumia 900 Windows Phone is a bit unique in that they are made from re-cycled materials (plastic from water bottles). Ecolife cases are environmentally friendly, durable and a nice choice if you prefer to carry your Windows Phone on your belt.
The Lumia 900 is a bit snug in the case but after a few days, the case relaxes just enough to get rid of the tightness. At both ends of the ELAN case is a stretchy material that helps give the case a little wiggle room as well. The ELAN case holds the Lumia 900 in place nicely with a large, magnet flap. The ELAN case is fitted with a wide belt clip that fits snugly on your belt. The wider belt clip reduces any wiggle the case may have while on the belt.
The case is well built with no loose seams present. I can attest that the Ecolife cases are durable in that I've been using one that has transitioned from the HTC HD7S to the Titan and now the Titan II. The cases will eventually show wear but that simply adds character to the case.
The only downside to the ELAN is the bottom cutout. The cutout gives you an access point to push up on the phone when removing it from the case. The problem comes into play when you place the Lumia 900 in the case button side down. The power button is fully exposed and is prone to accidental activation. You will need to make an assertive effort to place the Lumia 900 in this case button side up.
Otherwise, it's a very nice case for your Nokia Lumia 900. The ELAN case is currently running $19.95. You can find the Ecolife ELAN case for the Nokia Lumia 900 here at the WPCentral.com Accessory Store.
