Sturdy, I really like the concrete bottom. this will prevent my dogs from tipping it over and getting poison out.
The only reason I did not give it 5 star is the key. I had difficulty opening one of the side on one box.
It did not come with instruction. I had to go online to figure out how to open.
One of the box's key and bars were so far in and stuck in the little plastic bowl I could not get them out, thankfully there are 2 boxes and the key from one box opened the other.
Overall they seem like very good box.
Very Pleased with this Bait Station. Ordered two of them and received in great shape... Would have given them a 5 star rating but after the unpacking and checking everything out I noticed two units only came with 1 (one) key. Since I was using these at two different locations it is nearly impossible to use one key at two difference places at once. If you buy more than one you should get as many keys as units you purchase.... Really well made and I like the design.
