Greenhouse Megastore Junior Series Teaching Package - Finally, a commercial quality greenhouse at a price that will not break your budget. Don't let the price fool you; the frame of this structure is constructed from the same high quality, galvanized steel roll-formed components as our larger greenhouses. As such, this building can be engineered to meet almost any snow or wind load rating.

The 6mm twinwall polycarbonate covering offers an R-Factor of 1.55 which is only 0.02 less than 8mm coverings and comes with the same 10 year warranty. For these reasons and more, this "Junior" Series package is one of our most popular and will offer performance and reliability for generations of students.

Durability

All Garden Grower Hobby Greenhouses are engineered to meet 70 mph wind and 10 pound live load per the UBC Building Code. Even higher load ratings and stamped engineered plans are available at extra cost. All galvanized steel frame insures maximum strength and life. Lexan twin-wall polycarbonate covering is UV resistant and carries a 10 year warranty against discoloration. The Garden Grower uses the same steel components as utilized in our commercial structures.

Nice Idea But Won't Last With A Frenchie
Color: orange & blue, Color: orange & blue
My dogs loved the balls, however, withing 30 minutes, they were in pieces. Be careful because these parts can become choking hazards. Maybe they should try to make them a bit more sturdy, then I would buy again. Wish I could give them more stars because I liked them and the dogs did too.

Not a chew toy

Our dogs love these! The dogs play for about a half hour then they get tired ,they pick it up by the string and toss it around , only important thing, supervise play time !!! This will break if chewed on , this is not a chew toy , put away once your dogs are done with it .

Fits Cats not Dog size
Color: red&green
Sure these balls are cute, but most definitely not a dog size. I wouldn’t waste your money, unless you own a cat!

Not durable
Color: red&green
The description says for cats and dogs. My 6lb mini poodle tore it up in less than 40 minutes. The red one worked but the green one wouldnt even turn on. The indicator said it was fully charged but u plugged it in for a short time but nothing. I dont know if i can get a refund or not since the cover on the red one has been completely torn off. I dont recommend this product

This is an awesome toy for dogs and cats!
Color: red
This is such a cool toy for a dog or a cat. I bought it for my 28 pound Aussie doodle. She’s slightly laid up after an injury recently so I’m trying to come up with things she can play with in the house without excessive running. This totally keeps her engaged and she loves it. But I have to watch her because every once in a while she’ll just catch it and try and chew on the ball! But I’ve been sharing it with my neighbor who has a cat. She’s borrowing it today and her cat loves it too! It seems pretty durable overall but it certainly doesn’t want my dogs’s jaws trying to crack it into. You do hear a humming noise while it’s running but I think that’s to be expected. Mostly I just love how much it entertains both dogs and cats!!
