When it comes to novelty / decorative lighting, there's a fine line between tacky and desirable.
The squeezable Oggz are made of flexible plastic, with a hard plastic base that can be easliy removed (and you will never get it back in!) The base of each Ogg(z?) has a tiny on/off switch, and some tiny protruding charging contacts.
Each Ogg automatically changes colour, and this cannot be controlled by the user.
The product photograph makes it look a lot better than it is. The concept is great, but the build quality lets the Oggz down. Sadly the base-station is made of quite tacky grey plastic, and when you place the Oggz (the individual egg-shaped lamps) on the base-station to charge, you have to mess around trying to align them, which can be fiddly and annoying. Charging is generally unreliable as the charging contacts which protrude from the lamps themselves are are quite poorly designed; the very slightest of knocks of the base-station can mean you are unknowingly discharging the lamps. This results in one or more lamps not working at any given point.
The colour change is neither subtle, calming, nor controllable. Not great for bedtime - especially when all three are turned on!
Get the Mathmos Aduki instead. Although you don't get three lamps with the similarly-priced Mathmos, the lamp is a little larger, it's far more beautifully sculpted, much more reliable (internal battery also lasts far longer), and you can control the colour changes, which are truly graduated between the three solid colours, or stop them altogether. I would recommend the Mathmos lamp over these Oggz, even for kids - but definitely for all who appreciate a nicely designed product.
