My project was to be a waterfall for a terrarium. Unfortunately, the fumes are so strong that you can not use it in the apartment. Processing could be the product relatively well. Unfortunately, the goods were probably damaged already in the delivery. The big dent caused a longer opening process and wandering of itself no longer read them afterwards. Therefore, the 2.5 kg had to be processed immediately, what a clever sealing contradicts (multiple applications). I would buy this product again as far as it does not damage arrives and can be closed again. Of course, the use outdoors needs to be.
