We purchased the 8' x 16' greenhouse and it looks great - the problem was that the instructions and the assembly videos on-line are not adequate - they make it seem so easy to assemble when in fact you need to pay close attention to what you are trying to build - by trial an error, I revised a number of the assembly procedures to improve the fit-up. There are additional improvements I would have liked to have made had I had the experience with the initial assembly. We have gotten great comments as to the look of the greenhouse and automatic roof vents work just as they are designed to - we are happy with our purchase but we still need to see how it holds up during the New England winter.
Ordering it thru Home Depot worked out great to - especially the delivery / pick-up aspect! The size we purchased came in 5 boxes which easily fit into 2 SUV's and the boxes were labeled and filled with the necessary parts. It was beneficial to layout and assemble al of the like parts together as well.

I would probably recommend it overall (for the price) BUT any potential purchaser needs to be aware that the lower (clear) windows are incredibly flimsy (thin) - and buckle very easily e.g. if you happen to press against, or push, them for any reason be careful they don't pop out. However, the main issue we have with the greenhouse is that the green horizontal struts on the 1st level down from the top (e.g. in line with bottom of the window opening) are about 1/2" - 3/4" too short (& so the connectors at each end of these don't really hold them in place very well) which means it slides either left or right, resulting in almost 1" gaps in the roof which allows the rain to come in. We are trying to find a solution to this. Once put together, the greenhouse looks pretty good.

The installation was relatively smooth. Careful attention to the instructions is required. Customer support was very helpful when parts had to be replaced.
Kudos for the overall fit of components. The further into the installation the stronger the unit became. We will need to install an exhaust fan to draw the heat out. The roof vents are not enough to regulate temperature. The one caveat don't be mislead by the videos and assembly time.
which says completed in 2 days , 2 weeks is more realistic. But in the end the Rion appears to be a solid product. It has already withstood some high wind conditions with no damage.

Very dissatisfied with this product. Very cheaply made for the large amount of money it costs. I would NOT recommend this product to anyone. Advertising is very misleading, it is NOT quick and easy setup. States lock and pin system, unfortunately you find out after its been delivered what their version of that means. I have wasted almost $2500 on a flimsy cheap greenhouse.

Assembly was fairly simple when you follow the directions step by step and have a lot of patience. Also, fit the pieces together before fastening. As with any molded products, you may find excess edges you may need to trim (specifically the polycarbamate panels). I am using it as a solarium where I have my smoker set up and next to a fire place on my deck (cheaper than spending $15,000 to $30,000). I left out two of the rear polycarbamate panels and the lower center upright while reinforcing the inside of the horizontal cross tubes with a 3 ft long 1/2" electrical conduit. I gave it a four due to the roof center caps being snap together rather than fastened with screws. One of the caps blew off in the heavy wind and in order to put it back on I had to disassemble two of the roof panels. I then used stainless steel screws to fasten them down this time. I am amazed how solid this is once finished. Amazing sitting buy a fire outside your house in a thunderstorm and staying completely dry!

This little greenhouse looks terrific but I don't think it's insulated enough for over wintering. It was difficult to put together because the pieces didn't always want to go together. The screws were not numbered but just about everything else was. It requires a lot of patience to put together. I love the look and will enjoy working in it. The vent window wasn't well thought out. We had to make it more secure so the wind doesn't catch it and blow it open.
