goodif [SEP] this is a potentially excellent product if you do not need it to be completely stable it wiggles some though if you put your weight directly over the leg and push straight up it is fine just do not expect it to be rock solid i have a regular grab bar on the right side and use the left support rail only and that is fine because the two rails are not directly connected so you can use one rail or both but as a big guy lbs i would be nervous if i did not have the grab bar even though it is rated for lbs it would be perfect for a smaller person who just needs a boost but it could be potentially dangerous if a larger person with serious balance problems fell sidewaysnote too that this will not work with a piece toilet that curves upward from seat to tank the connector piece needs about inches of flat space behind the seatpros works only with a traditional toilet wiggles to the left and right adjusting width and height might be difficult or impossible for a person with poor hand strength the spring loaded buttons are stiff made in china but what is not these days
