## Questions & Answers

**Q: How easy is it to put on?**
A: My daughter had a cast from wrist to arm pit so was a little tricky to get round her elbow the first time. But after that it was fairly easy and worked a treat.also leant it to a friend who found it a god send x  my daughter is 9 but fairly small for her age but this size fit perfect. Hope this helps

**Q: My daugher has had a op to put her nail back on a finger and stitches. Been told not to get wet at all, going on holiday Wednesday ! How good are they**
A: They are extremely good and she will be able to fully enjoy the water. The important thing is to put them on correctly, getting all the air out by gently lowering the arm into the water and allowing the air to escape and then sealing it firmly to her arm without creases. At this point it’s completely water tight.

**Q: i have had surgery on my hand and elbow and told no water whilst in shower, as a lady with larger bones should I buy M or L**
A: We would always recommend measuring you can do so by measuring the length from the finger tips to above the affected area and the circumference is around the skin at the top of the area that needs to be covered. We would also suggest our Adult Full Arm cover but do understand if your measurements do not fit with this.

**Q: How do you get it flat against the skin by the armpit as my son is in tears with it being so tight?**
A: Sorry but we didn't have any problems.  It was tight but not so tight that it hurt so maybe your son may need the next size up.  Don't know if this is a good suggestion or not but maybe try a bit of talcum powder under the band although I am not sure if this may compromise the seal but it might be the stickiness of the rubber which is causing the issue.  Hope you manage to get it more comfortable.
